House Republicans’ report contradicts witness account of Trump’s wheel-grab

US House Republicans on Monday released a report they said contradicted sensational January 6 committee testimony in which a former aide to Donald Trump described being told that as the attack on Congress unfolded, the then president was so eager to join supporters at the Capitol he tried to grab the wheel of his car.

“The testimony of … four White House employees directly contradicts claims made by Cassidy Hutchinson and by the select committee in the final report,” read the report by the House administration subcommittee on oversight, which searched for alleged bias or malpractice in the January 6 investigation.

“None of the White House employees corroborated Hutchinson’s sensational story about President Trump lunging for the steering wheel of the Beast,” the report said, referring to the colloquial name for cars that carry the president.

“Some witnesses did describe the president’s mood after the speech at the Ellipse. It is highly improbable that the other White House employees would have heard about the president’s mood in the SUV following his speech at the Ellipse, but not heard the sensational story that Hutchinson claims Anthony Ornato, the White House deputy chief of staff for operations, told her after returning to the White House on January 6.”

Hutchinson, a former aide to Trump and his final chief of staff, Mark Meadows, testified before the January 6 committee in private and in public.

In public, her testimony about Trump’s anger at his inability to overturn his defeat by Joe Biden made her a star witness, compared by some to John Dean, the White House counsel whose testimony sealed Richard Nixon’s fate in the Watergate scandal.

In especially memorable testimony, Hutchinson described what she said Ornato told her about Trump’s reaction, after telling supporters to “fight like hell”, to being told he could not go with them to the Capitol, to try to block election certification.

According to Hutchinson, Ornato said Trump furiously lunged for the wheel before a Secret Service agent grabbed his arm and said: “Sir, you need to take your hand off the steering wheel. We’re going back to the West Wing. We’re not going to the Capitol.”

Hutchinson said she was told “Trump then used his free hand to lunge towards Bobby Engel [an agent] and when Mr Ornato recounted the story to me, he motioned towards his clavicles”.

Questioned by Liz Cheney, an anti-Trump Republican and January 6 committee vice-chair, Hutchinson said Engel did not dispute the account. It was soon reported that Engel did dispute it, and wanted to testify under oath.

Among transcripts released on Monday, the unnamed agent who drove Trump said: “The president was insistent on going to the Capitol. It was clear to me he wanted to go to the Capitol.

“He was not screaming at Mr Engel. He was not screaming at me. Certainly his voice was raised, but it did not seem to me that he was irate – [he] certainly … didn’t seem as irritated or agitated as he had on the way to the Ellipse,” the area near the White House where Trump addressed supporters.

The driver added: “I did not see him reach. He never grabbed the steering wheel. I didn’t see him, you know, lunge to try to get into the front seat at all. You know, what stood out was the irritation in his voice, more than his physical presence.”

The transcript was among those the January 6 committee did not release, citing security concerns. The transcripts were eventually released with redactions.

On Monday, the New York Times said former January 6 committee aides said its final report included details of the driver’s interview and no cover-up was attempted.

The final report said: “The committee has now obtained evidence from several sources about a ‘furious interaction’ in the SUV. The vast majority of witnesses who have testified before the select committee about this topic, including multiple members of the secret service, a member of the Metropolitan police, and national security and military officials in the White House, described President Trump’s behavior as ‘irate’, ‘furious’, ‘insistent’, ‘profane’ and ‘heated’.”

It also said: “It is difficult to fully reconcile the accounts of several of the witnesses who provided information with what we heard from Engel and Ornato. But the principal factual point here is clear and undisputed: President Trump specifically and repeatedly requested to be taken to the Capitol. He was insistent and angry, and continued to push to travel to the Capitol even after returning to the White House.”

On Monday, Barry Loudermilk of Georgia, the Republican select committee chair, said the report showed “firsthand testimony directly contradicts Cassidy Hutchinson’s story and the [January 6] committee’s narrative. Although the committee had this critical information, they still promoted Ms Hutchinson’s third-hand version of events.”

Now 27, Hutchinson has released a memoir and become a prominent figure on the anti-Trump right. On Monday, her attorney re-released a letter to Loudermilk first sent in January.

“Since Ms Hutchinson changed counsel,” the letter said, referring to her decision to stop using lawyers provided by Trump, “she has and will continue to tell the truth.

“While other individuals … would not speak with the select committee, Ms Hutchinson and many other witnesses courageously stepped forward. Yet she now finds herself being questioned by you and your subcommittee regarding her testimony and on matters that may also be the subject of ongoing criminal proceedings against Mr Trump.”

Trump, 77, is the presumptive Republican nominee to face Biden again in the fall. He still faces 91 criminal charges, 17 concerning attempted election subversion. Though Trump was impeached for inciting an insurrection, Senate Republicans assured his acquittal.

Hutchinson, her lawyer said, would not “succumb to a pressure campaign from those who seek to silence her”.
