A DHS report on Jan. 6 could drop soon. It could be bad for the Secret Service.

As the Secret Service fields a barrage of investigations on the Trump shooting, it is also set to face the release of a report on another bruising episode: its response to the Jan. 6, 2021, attack on the Capitol.

Investigators in the Inspector General’s Office for the Department of Homeland Security — the Secret Service’s parent agency — have finished a long-awaited report on the violence that day and shared it with the Secret Service to review, a standard practice. The report, which could cast light on a series of embarrassing security lapses for the agency, could be released as soon as this week, according to a congressional aide briefed on the matter and granted anonymity to discuss private conversations. Sensitive reports sometimes take longer than anticipated to become public.

The Department of Homeland Security Headquarters also signs off on such reports before their release, but it is unclear if it has done so yet. The report’s status was also detailed in a document reviewed by POLITICO.

Questions have persisted about how the various law enforcement agencies protecting the Capitol on Jan. 6 shared intelligence on the danger posed by a crowd of pro-Trump rioters who stormed the building in an effort to prevent the certification of Joe Biden’s electoral victory. Before the violence broke out, Secret Service personnel learned that many Trump supporters chose not to attend a speech Donald Trump gave on the Ellipse when they learned at security checkpoints that their weapons would be confiscated.

The Secret Service also faced opprobrium for deleting some text messages its agents sent connected to the day of the attack. The agency claimed that those deletions resulted from a routine systems migration, but Hill Democrats and transparency groups have said the explanation doesn’t hold up. DHS’ Inspector General also drew criticism for the text message disappearances because investigators in that office reportedly learned about the deletions in early 2021 but waited months to tell lawmakers.

Nick Schwellenbach, an investigator at the government watchdog group Project on Government Oversight, said the text message incident raises questions about the Inspector General’s ability “to robustly and impartially conduct oversight of the Secret Service in highly charged political situations.”

A spokesperson for the Secret Service referred a comment request to DHS headquarters. DHS headquarters referred a request for comment to the Office of the Inspector General. That office did not respond to requests for comment.

Multiple people under Secret Service protection faced grave danger Jan. 6, including Vice President Mike Pence, who nearly ran into members of the mob in the building who were only diverted by a quick-thinking Capitol Police officer. The rioters were animated by rage against Pence after he refused to block the certification of Electoral College votes to help Trump stay in power, and many of them chanted for him to be hanged. He took shelter in a secure room in the Capitol Building, but the Secret Service has faced criticism for letting him come so close to injury or worse.

Others who were close to danger that day included Kamala Harris, then the vice president-elect, who was evacuated from the Democratic National Committee headquarters that morning when a bomb was discovered in front of the building.

DHS’s Inspector General may be the last major investigative entity to release a report on the violence. And leaders of the office itself have been beset by accusations of wrongdoing in recent years. The Council of the Inspectors General for Integrity and Efficiency (CIGIE) — an umbrella group that oversees inspectors general — has spent years investigating the head of the DHS Inspector General’s Office, Joseph Cuffari, over allegations he retaliated against a whistleblower in his office.

Investigators working on that probe have circulated a report in recent weeks, sharing it with people it mentions, according to two people who read redacted versions of the document, but it is unclear what conclusions the report reached. CIGIE is required to share the report with Congress, but not to make it public.

But Cuffari has said that a bevy of inquiries from CIGIE has hindered his office’s effectiveness. In a lawsuit he filed against the group last year, Cuffari alleged that employees in his office had to spend 800 hours fielding scrutiny from CIGIE about “obviously meritless grievances.”

Meanwhile, friction has also persisted between his office and DHS headquarters. Cuffari’s team has accused department leadership of stymieing the Inspector General’s investigations, including in a letter sent Jan. 17 and reviewed by POLITICO. Headquarters, meanwhile, has maintained that it has followed the laws and policies governing the Inspector General’s access to records.
