Former President Donald Trump tried to phone a witness in the House select committee’s investigation of last year’s Capitol riot, the panel’s vice chair revealed near the conclusion of Tuesday’s hearing.

“That person declined to answer or respond to President Trump’s call and instead alerted their lawyer,” Rep. Liz Cheney (R-Wyo.) said in her closing statement. “Their lawyer alerted us and the committee has supplied that information to the Department of Justice.”

“Let me say one more time,” Cheney added. “We will take any efforts to influence witness testimony very seriously.”

The lawmaker did not identify the witness apart from saying that their testimony had not been part of the public hearings and noted that the attempted call by Trump took place after the panel’s previous hearing June 28.

Cheney has previously raised concerns that people close to the 45th president or others in his orbit may have contacted witnesses in an inappropriate attempt to influence their testimony.

During the June 28 hearing — which featured bombshell testimony from Cassidy Hutchinson, a former aide to Trump chief of staff Mark Meadows — Cheney revealed statements from two witnesses who said they had been contacted by people attempting to influence their testimony.

“What they said to me is, as long as I continue to be a team player, they know that I’m on the team,” one of the witnesses said. “I’m doing the right thing. I’m protecting who I need to protect, you know, I’ll continue to stay in good graces in Trump World. And they have reminded me a couple of times that Trump does read transcripts and just to keep that in mind as I proceed through my depositions and interviews with the committee.”

The second witness recounted receiving a voice mail message that said: “[A person] let me know you have your deposition tomorrow. He wants me to let you know that he’s thinking about you. He knows you’re loyal, and you’re going to do the right thing when you go in for your deposition.”

Federal law prohibits using force, threats, intimidation or coercion to alter or attempt to wrongly change someone’s testimony in an ongoing federal proceeding. Any decision on charges would be left to the Department of Justice.

There was no immediate response from the former president, who criticized Cheney and the panel earlier Tuesday as the “Unselect Committee of Political Hacks and Thugs” on his Truth Social platform.
