Don Jr to introduce Trump’s vice-president pick at Republican convention

Donald Trump ’s running mate will be introduced at the Republican national convention next Wednesday by his eldest son, according to people familiar with the matter, raising speculation that Senator JD Vance will be named the vice-presidential pick after being endorsed by Don Jr.

The fact that Don Jr will speak immediately before the running mate delivers remarks, earlier reported by Axios, is seen as notable inside the Trump campaign because of Don Jr’s close ties to Vance.

Still, a person directly familiar with the matter cautioned that the speaking schedule was decided three to four weeks ago and they were uncertain how instructive Don Jr’s involvement was.

Trump has said he wants his running mate to be revealed at the convention next week in Milwaukee, Wisconsin, but due to convention rules that require the ticket to be nominated by the first day, the former president has been forced to make a decision before Wednesday.

For months, Trump has presided over a characteristically theatrical selection process in which he made dramatic pronouncements at rallies in an effort to drive media speculation before narrowing the list to a final three: the North Dakota governor, Doug Burgum, Senator Marco Rubio and Vance.

The leading contenders have run through an emotionally draining fight to be Trump’s running mate, defending the former president in cable news interviews, mingling with members at Trump’s Mar-a-Lago club, coalescing support from Trump allies and trying to appeal to Trump’s core Maga voters at rallies.

The Guardian has previously reported that Trump has told allies he wants a running mate who would be a “fighter” – someone who is media-savvy and will defend him on adversarial TV networks – and loyal to the extent that they would be “everything Mike Pence wasn’t”.

Trump’s former vice-president was a valuable asset during the 2016 and 2020 campaigns because of his Christian conservative credentials that shored up support among Republicans who were suspicious of the thrice-married reality TV star.

But Pence’s refusal to do one final favor and comply with Trump’s demand to block the certification of the 2020 election results in Congress led to a falling-out, and made Pence the target of the January 6 Capitol attack rioters.

For his 2024 campaign, Trump is seeking a “Goldilocks” running mate: strong but loyal, in tune with Maga but not over-rehearsed, telegenic but not likely to outshine him. His choice will go up against Kamala Harris, the first Black woman to serve as vice-president.

Vance, the junior senator from Ohio, has increasingly fit that profile.

On Sunday, Vance said on NBC’s Meet the Press that he supported Trump’s vow to appoint a special counsel to prosecute Joe Biden, making apparent references to the House oversight committee’s search for evidence of impeachable conduct by Biden, which it has not found.

Vance also suggested it was reasonable for Trump to prosecute Biden on the grounds that Biden had supposedly weaponized the legal system against him, although there is no evidence Biden has been involved in prosecutorial decisions at the justice department or elsewhere.

The NBC anchor Kristen Welker pressed Vance on his support for a special counsel: “If it’s not OK for Joe Biden to weaponize the justice department – as you say, which there’s no evidence of that – why is it OK for Donald Trump to do that?” she asked.

Vance repeated the common complaint among Republicans that one former justice department official took a job as a prosecutor in the New York criminal case in which Trump was convicted of 34 felony counts of falsifying business records to influence the 2016 election with a hush-money scheme.

“If Donald Trump’s attorney general had his No 2 or his No 3 jump ship to a local prosecutor’s office in Ohio or Wisconsin, and that person then went after Donald Trump’s political opposition, that’s a different conversation,” he said, though the prosecutor at issue was not as senior as the hypothetical.

Trump has repeatedly vowed to prosecute his political enemies, sharing posts on his Truth Social website that advocated jailing top Democrats and Republicans who criticized him, including one that said the former House Republican Liz Cheney should face “televised military tribunals”.
