Vice Chair Liz Cheney said, in closing the hearing, that Trump himself tried to call a witness who she said has not yet publicly testified.
“After our last hearing, President Trump tried to call a witness in our investigation — a witness you have not yet seen in these hearings,” she said.
Cheney said the witness did not answer the call.
“Their lawyer alerted us, and this committee has supplied that information to the Department of Justice,” she said.
“Let me say one more time, we will take any effort to influence witness testimony very seriously,” she added, as the committee continually warns against witness tampering in its ongoing investigation.
