US conservative commentators say they are 'victims' of alleged Russian disinformation campaign

US conservative commentators have responded to the unsealed US Department of Justice indictment that accuses “Two RT Employees [of] Covertly Funding and Directing US Company that Published Thousands of Videos in Furtherance of Russian Interests”.

The release does not name the company. It says that it is “a Tennessee-Based Online Content Creation Company”, and refers to it as “Company 1”.

The Guardian’s Andrew Roth reported on Wednesday that the Biden administration has accused Russia of carrying out a sustained disinformation campaign targeted at American voters and meant to influence the outcome of November’s presidential elections.

In its most direct accusation of election meddling to date, the US government accused the state-financed RT (formerly known as Russia Today) and other Russian state-backed media of spearheading a covert campaign of disinformation promoting pro-Kremlin views laundered through their online and television networks.

The treasury department also sanctioned the RT’s editor-in-chief, Margarita Simonyan, and nine other employees of the network over the aggeled campaign of disinformation around the elections. Simonyan is a “central figure in Russian government malign influence efforts” the department alleged.

Conservative podcaster Tim Pool posted a statement on Twitter / X “regarding allegations and the DOJ Indictment”, saying, “Should these allegations prove true, I as well as the other personalities and commentators were deceived and are victims.”

Conservative commentator and YouTuber Benny Johnson said an hour ago, “A year ago, a media startup pitched my company to provide content as an independent contractor. Our lawyers negotiated a standard, arms length deal, which was later terminated. We are disturbed by the allegations in today’s indictment, which make clear that myself and other influencers were victims in this alleged scheme”:

Here is AP’s report following Harris on the campaign trail today:

Vice President Kamala Harris used a campaign stop in New Hampshire on Wednesday to propose an expansion of tax incentives for small businesses, a pro-entrepreneur plan that may soften her previous calls for wealthy Americans and large corporations to pay higher taxes.

Describing small businesses as “an essential foundation to our entire economy,” Harris said she wants to expand from $5,000 to $50,000 tax incentives for startup expenses, with the goal of eventually spurring 25 million new small business applications over four years.

The speech was part of Harris’ effort to strengthen her economic credentials with only two months until the end of the election.

“You’re not only leaders in business. You’re civic leaders,” Harris said. She added, “You are part of the glue and the fabric that holds communities together.”

The vice president spoke at the Throwback Brewery in North Hampton, outside Portsmouth, and met with co-founders Annette Lee and Nicole Carrier. Their brewery got support to open its current location through a small business credit and installed solar panels using federal programs championed by the Biden administration.

After that, Harris visited another women-owned small business, Port City Pretzels, which was founded in 2015 and had expanded out of its original, 500-foot facility into a larger location. One of the co-owners, Suzanne Foley, led Harris around brown boxes bearing the company’s logo, some stacked head-high and waiting to be shipped to customers around the country.

“Thank you for visiting our little company,” said Foley, who beamed and chatted with Harris as the pair walked around the facility. At one point, the vice president asked of the pretzels “Is it a family recipe?” When the answer came back yes, she offered, “Is it a secret family recipe?” Foley responded, “It’s not really, no.”

More now on Cheney’s endorsement, via the Associated Press:

Former Republican Representative Liz Cheney on Wednesday said she would support Kamala Harris for president, ending weeks of speculation about how fully the member of a GOP dynasty-turned-Trump critic would embrace the Democratic ticket.

Cheney, who co-chaired the House investigation into the 6 January 2021, attack, became a fierce Trump critic and was ousted in her 2022 Republican primary in Wyoming as a result, made her announcement at an event at Duke University. In a video posted on the social media network X, she finished by talking about the “danger” she believed Trump still poses to the country.

“I don’t believe that we have the luxury of writing in candidates’ names, particularly in swing states,” she said. “As a conservative, as someone who believes in and cares about the Constitution, I have thought deeply about this. Because of the danger that Donald Trump poses, not only am I not voting for Donald Trump, but I will be voting for Kamala Harris.”

The daughter of former vice president Dick Cheney, Liz Cheney has been perhaps Trump’s highest-profile Republican critic. She joins other Republicans like her former 6 January committee member, former Representative Adam Kinzinger and former Rep. Denver Riggleman, as backers of Harris. More than 200 alumni of the Bush administration and former Republican presidential campaigns of the late Sen. John McCain and Sen. Mitt Romney also announced their endorsement of Harris last week.

Cheney was in House Republican leadership at the time of the 6 January attack but broke with most of her caucus over Trump’s responsibility. She lost her leadership post and was one of the few Republicans willing to serve on the 6 January committee, which was appointed by Democrats who controlled the House at the time.

11.32pm BST

Who is Liz Cheney – and why does her endorsement matter?

Liz Cheney, the daughter of Dick Cheney, who was president under George W Bush, is often described as Republican party royalty – and is an outspoken critic of Donald Trump.

She was chair of the January 6 committee, and has described Trump as “unstable” and “depraved”, according to the New York Times.

But it was uncertain whether she would endorse Harris, or stop just short of that. At an event at Duke University on Wednesday evening, she said that she would be voting for Harris.

On Monday this week, 200 Republicans who worked for President George W Bush and the former presidential candidates Senators Mitt Romney and John McCain, released an open letter in support of Harris and her running mate, the Minnesota governor, Tim Walz .

The letter warned that there was more to fear from Trump than a repeat of his first term because he is now bound up with the authoritarian plan to impose rightwing control across the entire US government, including non-partisan federal agencies, known as Project 2025 .

The Guardian’s Callum Jones reports that Donald Trump ’s tiny social media empire has seen its extraordinary stock market rally wiped out by a steep sell-off.

Shares in Trump Media & Technology Group, owner of Truth Social, closed below $17 on Wednesday, reversing all their gains since the company’s rapid rise took hold in January.

The former president has been prohibited by a lock-up agreement from starting to sell shares in the firm until late September. While his majority stake in the firm is still worth some $2bn on paper, its value has fallen dramatically from $4.9bn in March.

As a business, TMTG is not growing rapidly. It generated sales of just $4.13m in 2023, according to regulatory filings, and lost $58.2m.

Nor is Truth Social growing rapidly as a platform. While TMTG has not disclosed the size of its user base, the research firm Similarweb estimated that in March it had 7.7m visits – while X, formerly Twitter, had 6.1bn. That same month, however, TMTG was valued at almost $10bn on the stock market.

The former president is potentially on the hook for hundreds of millions of dollars’ worth of penalties following two civil trials, taking a significant chunk out of his personal fortune. Trump Media has, however, previously insisted that there is no “conceivable sign anywhere” that Trump plans to sell shares in TMTG.

The rules for the 10 September debate of the Democratic and Republican presidential candidates will include muting microphones, a source told Reuters.

A Republican-led House committee sent a subpoena to Minnesota’s governor, Tim Walz , seeking documents and communications related to a vast fraud scheme conducted by a non-profit that used pandemic relief funds meant for feeding kids.

NBC News first reported the subpoenas, which were sent to Walz; Minnesota’s commissioner of education, Willie Jett ; the US agriculture secretary, Tom Vilsack ; and the agriculture inspector general, Phyllis Fong .

The House committee on education and the workforce wrote to Walz to say it had been investigating the Department of Agriculture and the Minnesota department of education’s oversight of federal child nutrition programs and Feeding Our Future, the group that is alleged to have stolen more than $250m in pandemic funds.

The subpoena does not seek an in-person appearance from Walz before the committee. It sets an 18 September deadline for turning over documents.

Five of the people involved in the scheme were convicted for their roles earlier this year in a trial that included an attempt to bribe a juror with a bag full of $120,000 in cash left at her home. In total, 70 people have been charged in relation to the scheme.

The Harris campaign has not said whether Kamala Harris supports requiring automakers to build only electric or hydrogen vehicles by 2035 – a position that she held during her 2020 presidential campaign.

According to Axios, the Harris campaign has sent contradictory signals about her position on a mandate for automakers, a key issue in pivotal battleground states including Pennsylvania, Michigan and Wisconsin, where many autoworkers are based. The report says:

In a lengthy ‘fact-check’ email last week that covered several issues, a campaign spokesperson included a line saying that Harris ‘does not support an electric vehicle mandate’ – suggesting she changed her previous position, without elaborating.

When asked to clarify Harris’s position, the campaign declined to comment, according to the report.

Harris vows to make tax code 'more fair' in New Hampshire speech

Kamala Harris says she will make the US tax code “more fair” while also prioritizing investment and innovation.

“Billionaires and big corporations must pay their fair share in taxes,” she tells her supporters. “That’s why I support a billionaire minimum tax and corporations paying their fair share.”

She says that while her administration will ensure that the wealthy and big corporations pay their fair share, it will also tax capital gains “at a rate that rewards investment in America’s innovators, founders and small businesses”.

If you earn a million dollars a year or more, the tax rate on your long-term capital gains will be 28% under my plan. Because we know when the government encourages investment, it leads to broad based economic growth, and it creates jobs, which makes our economy stronger.

Updated at 9.08pm BST

Kamala Harris says she will also invest in small businesses and innovators throughout America, noting that “talent exists everywhere in our country” but that not everyone has access to the financing, venture capital or expert advice.

She says that if elected, her administration will expand access to venture capital, support innovation hubs and business incubators, and increase federal contracts with small businesses. Small businesses in rural communities will be a particular focus, she says.

8.22pm BST

Kamala Harris says she will also help existing small businesses to grow, by providing low- and no-interest loans to small businesses that want to expand.

She also pledges to “cut the red tape that can make starting and growing a small business more difficult than it needs to be”.

For example, Harris says she will make it cheaper and easier for small businesses to file their taxes.

Let’s just take away some of the bureaucracy in the process to make it easier for people to actually do something that’s going to benefit our entire economy.

Kamala Harris moves on to talking about what she calls an “opportunity economy”, which she envisions is a one “where everyone can compete and have a real chance to succeed”.

She says America’s small businesses are an “essential foundation to our entire economy” and that she wants to see 25m new small business applications by the end of her first term, if she is elected.

To help achieve this, Harris says she will lower the cost of starting a new business. It costs about $40,000 to start a new business, she says, and the current tax deduction for a startup is just $5,000.

Harris proposes to expand the tax deduction for startups to $50,000, which she says is essentially “a tax cut for starting a small business”.

“We cannot continue to accept this as normal,” he added. He said he was closely coordinating with officials at the federal, state and local level.

Biden also called on Republicans in Congress to work with Democrats to pass “common-sense” gun safety legislation, adding:

We must ban assault weapons and high-capacity magazines once again, require safe storage of firearms, enact universal background checks and end immunity for gun manufacturers. These measures will not bring those who were tragically killed today back, but it will help prevent more tragic gun violence from ripping more families apart.

RT editor-in-chief covertly recruited US influencers to spread pro-Kremlin messages, says treasury department

The US treasury department announced sanctions against the Russian state media network RT’s editor-in-chief, Margarita Simonovna Simonyan, and nine others affiliated with the network over what it said were efforts to meddle in the 2024 presidential election.

It said that beginning in early 2024, RT executives began a “nefarious effort to covertly recruit unwitting American influencers in support of their malign influence campaign”.

Simonovna Simonyan is a “central figure in Russian government malign influence efforts” and allowed RT to used a front company to disguise its own involvement or the involvement of the Russian government in content meant to influence US audience, the department said.

Other RT employees included in the latest sanctions are the network’s deputy editor-in-chief, Elizaveta Yuryevna Brodskaia , who the US said has reported to Russia’s president, Vladimir Putin; deputy editor-in-chief Anton Sergeyvich Anisimov, who the US said “conducts activities on behalf of the Russian Federal Security Service (FSB); deputy director of RT English-language broadcasting Andrey Vladimirovich Kiyashko ; digital media projects manager Konstantin Kalashnikov ; and Elena Mikhaylovna Afanasyeva , who the US said “covertly interacted with prominent US social media influencers under the cover of a fake persona”.

Merrick Garland says Americans have right to know 'when foreign power attempts to exploit' US

The US attorney general, Merrick Garland, speaking before a meeting of the justice department’s election threats taskforce, said the American people “are entitled to know when a foreign power is attempting to exploit our country … to send around its own propaganda”.

Garland accused the Russian government of using the state-backed media outlet RT to “direct disinformation and propaganda” in the wake of Russia’s full-fledged invasion of Ukraine.

As part of that effort, RT and its employees implemented a nearly $10m scheme to direct a Tennessee-based company to contract US-based social media influencers to disseminate content “deemed favorable to the Russian government”, he said.

In a separate enforcement action, the justice department is seizing 32 internet domains that it alleges the Russian government has used “to engage in a covert campaign to interfere and influence the outcome of our country’s elections”, he said.

Interim summary

Hello, live blog readers, it’s never a dull day when there’s an election, especially one as pivotal as the 2024 presidential election . We’ll bring you news developments as they happen, so stick with the Guardian.

Here’s where things stand:

• The US plans to accuse Russia of a sustained effort to influence the election by using Kremlin-run media and other online platforms to target US voters with disinformation, according to reports. The Biden administration will reportedly announce a series of actions later today in connection with such allegations.

• A top strategist to the UK prime minister, Keir Starmer , will brief Kamala Harris ’s presidential campaign on Labour’s election-winning strategy, according to a report. Deborah Mattinson , Starmer’s polling expert who was his director of strategy while he was leader of the opposition, will reportedly travel to Washington DC next week.

• A fundraising event for some of the rioters who attacked the US Capitol on 6 January 2021, aiming to prevent the certification by Congress of Joe Biden ’s election victory over Donald Trump , was scheduled to take place today at Trump’s golf club in New Jersey – but has been postponed indefinitely.

• Kamala Harris will travel to Pittsburgh on Thursday to prepare for next week’s presidential debate, according to multiple reports. The US vice-president and Democratic nominee for president will spend the final days leading up to the debate on 10 September in Pittsburgh, the reports say, where she will also hold informal meetings with voters in the battleground of Pennsylvania, a crucial swing state.

• National polls for the US presidential race have been upended ever since Kamala Harris took over from Joe Biden to run against Donald Trump. While Biden was trailing the Republican former president nationally and in many crucial swing states, Harris has gained about three points in national polls since becoming the nominee. The Guardian’s poll tracker assesses polls over a rolling 10-day period. It now has Harris leading nationally by about two points.

• A Republican anti-Donald Trump group is targeting disaffected Republicans and conservative-leaning independents in a new $11.5m ad campaign that will play in key battleground states . The ad buy, by Republican Voters Against Trump , targets voters in swing states and features former Trump voters explaining why they plan to vote for Harris in November.

Ginni Thomas, the far-right activist wife of the supreme court justice Clarence Thomas, has thanked a religious liberties group for its efforts to block reforms of the court aimed at reining in the justices’ ethical breaches, including those of her husband.

A new recording obtained by the investigative website ProPublica and the watchdog Documented discloses a July email in which Ginni Thomas thanked First Liberty Institute for fighting to oppose supreme court reforms. She specifically referred to White House proposals from Joe Biden designed to rein in wayward justices on the country’s highest court, of which her husband is the prime example.

The email was read out by the head of First Liberty Institute, Kelly Shackelford, on a 31 July call with donors to the group. He said the email had been written by Ginni Thomas that same day.

Two days previously, Biden had called for sweeping changes to the court, including term limits for the nine justices and a code of ethics that would be enforced by an outside body. Under current arrangements, the justices are liable to a voluntary code which they individually police themselves.

In an op-ed piece in the Washington Post , the US president explained why he thought a tougher code of ethics was now necessary. He pointed to “scandals involving several justices” that had damaged public confidence in the court, including “undisclosed gifts to justices” and “conflicts of interest connected with Jan 6 insurrectionists”.

Biden did not mention names, but Clarence Thomas has been implicated in both types of ethically questionable behaviour. ProPublica has exposed the lavish international travel that the justice enjoyed courtesy of the Republican mega-donor Harlan Crow.

The Biden administration is reportedly planning to accuse Russia of Kremlin-sponsored attempts to target US voters with disinformation in a sustained effort to influence the 2024 presidential election.

According to reports, the White House is expected to publicly condemn Moscow on Wednesday alongside an announcement by the justice department of law enforcement action targeting the covert Russian campaign.

As we reported earlier, the Russian state media network RT is expected to be a major focus of the US announcement. US intelligence agencies have flagged RT as a source of Russian propaganda and disinformation and required it to register as a foreign agent.

In July, the justice department accused a senior editor at RT of being involved in a Kremlin-backed scheme to spread online disinformation in the US, including about Russia’s war in Ukraine, using fictitious social media profiles posing as authentic Americans.

US officials are expected to also name the Social Design Agency , a Russian IT company that has already faced US sanctions for allegedly running fake news sites in Europe on behalf of the Russian government, according to CNN.

Republican Voters Against Trump, the group of disaffected Republicans devoted to stopping Donald Trump from returning to the White House, is stepping up its efforts with an $11.5m ad buy in critical battleground states.

The group is rolling out a new advert featuring former Trump voters vowing never again to back him, focused on the three so-called “blue wall” states of Pennsylvania , Michigan and Wisconsin , which Joe Biden won in 2020 and which Kamala Harris must retain in November.

The executive director of Republican Voters Against Trump, Sarah Longwell , told MSNBC that the thinking behind the ad buy was to give former Trump voters who are thinking about switching to Harris a “permission structure”. She said that focus groups had shown a “tremendous openness” among some Trump voters to backing the vice-president.

“We are taking Trump-voting voices and elevating them so it sends a signal to other Trump voters who are Kamala-curious,” Longwell said.

They are interested in voting for her either because Donald Trump presents such a threat, or because people are bored by Trump – they are bored with all the drama and tired of the insults.

In August, I attended a Maga -aligned tent revival in western Wisconsin, which promised hope, worship and healing. Much of the event, though, was political: speaker after speaker addressed topics like Covid-19 lockdowns, January 6 (an event one of the headlining speakers at the Courage Tour, Lance Wallnau , attended) and the importance of conservative Christians getting involved in politics.

One of the groups, called the Lion of Judah, is working to enlist poll workers to “fight the fraud” in November – an effort that extremism researchers worry could pose problems for election offices.

I spent some time digging into the Lion of Judah, and found that their course encourages participants to sign up as poll workers as “the first step on the path to victory this Fall”.

“That signals a very insidious desire to monkey around with the results of the election,” said Matthew Taylor , a researcher at the Institute for Islamic, Christian, and Jewish Studies whose work has focused on anti-democratic currents on the religious right.

Half of gen -Z voters said they will vote for Kamala Harris in November, according to a new NBC News poll published today.

The poll shows one-third of gen-Z voters said they plan to vote for Donald Trump , and 1 in 10 said they do not plan to vote in the presidential election.

Harris has the support of 60% of young voters who said they are “almost certain” they will vote in November.

The results of the poll show a significant gender gap: young women said they will vote for Harris by 30 points, while young men said they favor Harris by only four points over Trump.

Starmer strategist to brief Harris campaign on Labour's election-winning strategy – report

A top strategist to the UK prime minister, Keir Starmer , will brief Kamala Harris ’s presidential campaign on Labour’s election-winning strategy, according to a report.

Deborah Mattinson, Starmer’s polling expert who was his director of strategy for three years while he was leader of the opposition, will travel to Washington DC next week, Politico reported .

Mattinson will meet strategists from the Harris-Walz campaign and share insight on Starmer’s decisive path to victory in July’s UK election, it said.

A former colleague who worked alongside Mattinson on Labour’s campaign told the outlet that she wanted to “put the ‘hope and change stuff’ to one side” and maintain a ruthless focus on Harris’s appeal in swing states.

It comes after several of Starmer’s closest aides including Morgan McSweeney , now the head of political strategy in Downing Street, and Downing Street communications director Matthew Doyle traveled to Chicago for the Democratic national convention last month and met with members of the Harris campaign, the outlet said.

January 6 fundraiser at Trump's New Jersey golf club postponed indefinitely

A fundraising event for some of the rioters who attacked the Capitol on 6 January 2021 scheduled to take place today at Donald Trump ’s golf club in New Jersey has been postponed indefinitely.

The J6 Awards Gala, which was planned for Thursday at Trump’s Bedminster golf club, has been “postponed” and the location and time are to be announced, according to the event’s website .

Trump has been invited to speak at the event alongside confirmed speakers including his former lawyer and New York City mayor Rudy Giuliani, former Trump White House adviser Peter Navarro and Anthony Raimondi, a conservative influencer.

The event had been touted as a way to “honor and celebrate” some of the January 6 defendants “who have shown incredible courage and sacrifice”, with tickets ranging from $1,500 per person for general admission to $50,000 for a “platinum table” for 12 at the VIP reception.

The event website did not provide a reason for the postponement, but the New York Times said it had obtained text messages in which event planners cited “multiple issues outside of our control, the main one being safety concerns of attendees and staff”.

But national polling is only part of the picture. Hillary Clinton lost the 2016 election despite winning more votes than Donald Trump , because of the electoral system by which the president is elected.

The US presidential election is decided by races in individual states that have a set number of electoral college votes. This means the race is decided by a handful of swing states such as Pennsylvania, Arizona and Georgia.

Looking at data from RealClearPolitics , Kamala Harris has managed to at least close the gap on, if not overtake, Trump in the swing states. This is especially evident in Georgia and Arizona, where Harris has gained more than four points since Biden dropped out of the race.

Sitting ahead of Trump by a couple of points nationally is not enough to give Harris a secure lead in any of the swing states. Trump and Harris are still within two points of each other in seven swing states – well within the margin of error for polls.

Harris leading in polls but state-level data puts race on knife-edge

National polls for the US presidential race have been upended ever since Kamala Harris took over from Joe Biden to run against Donald Trump.

While Biden was trailing the Republican former president nationally and in many crucial swing states, Harris has gained about three points in national polls since becoming the nominee.

The Guardian’s poll tracker assesses polls over a rolling 10-day period. It now has Harris leading nationally by about two points.

But when comparing this performance with previous elections, data from RealClearPolitics reveals Harris’s lead over Donald Trump is weaker than those of his previous opponents. As of 30 August in their respective campaigns, Hillary Clinton led Trump by five points in 2016 and Joe Biden was ahead of him by 6.3 points in 2020.

“Donald Trump has destroyed the Republican Party,” a spokesperson for Republican Voters Against Trump said in a statement announcing the ad blitz.

And every election cycle he drives more and more Republicans to vote for Democrats, because they believe Donald Trump and the GOP candidates who imitate him are unfit for office.

The group says it helps elevate the voices of disaffected Republicans and “build a permission structure for many other traditional GOP voters to reject Donald Trump and his Maga movement, even if it means voting for Democrats with whom they might have policy differences.”"

Here’s the ad by Republican Voters Against Trump launched on Tuesday, which the group said is aimed at “conservative-leaning independents and undecided Republicans by featuring former [Donald] Trump voters who now support [Kamala] Harris .”

In the video, multiple former Trump voters talk about the dangers of a second Trump administration and about why they now support Harris.

The campaign also features 79 billboards showing former Trump voters from each swing state, with the messages: “I’m a former Trump voter. I won’t vote for Trump” and “I’m a former Trump voter. I’m voting for Harris.”

Republican anti-Trump group launches $11.5m ad buy

Good morning, US politics readers. With the general election just nine weeks away, a Republican anti- Donald Trump group is targeting disaffected Republicans and conservative-leaning independents in a new $11.5m ad campaign that will play in key battleground states .

The ad buy, by Republican Voters Against Trump , targets voters in Pennsylvania, Michigan, Wisconsin, Arizona and Nebraska and features former Trump voters explaining why they plan to vote for Kamala Harris in November.

Over the last few weeks, the Harris campaign has zeroed in on courting Republican voters , and more than 200 former GOP staffers declared their endorsement of the Democratic presidential candidate in an open letter last week. The Harris campaign also launched Republican Voters for Harris, which included more than 25 endorsements, and several Republican speakers were featured at the Democratic national convention last month, including former congressman Adam Kinzinger , the former lieutenant governor of Georgia Geoff Duncan and former Trump White House press secretary Stephanie Grisham.

Here’s what else we’re watching:

• Kamala Harris is expected to unveil a series of economic proposals at a campaign event in Portsmouth, New Hampshire, this afternoon.

• Donald Trump will be in Harrisburg, Pennsylvania, tonight for a town hall moderated by Fox News host Sean Hannity.

• Tim Walz will be in Pennsylvania today for campaign events in Lancaster and Pittsburgh.

• JD Vance will deliver campaign remarks in Mesa, Arizona, at an event hosted by the conservative group Turning Point Action.
