Cheney says Trump tried to personally contact a witness who hadn't yet testified before the Jan. 6 committee

Rep. Liz Cheney, the vice chair of the House select committee investigating the Jan. 6 attack on the U.S. Capitol, said at Tuesday's public hearing that former President Donald Trump tried to contact a witness who has not yet publicly appeared before the committee.

"Let me say one more time, we will take any effort to influence witness testimony very seriously," Cheney said. 

Cheney said Trump tried to call this person, who did not pick up and did not respond. Instead, they alerted their lawyer. The lawyer alerted the committee, and Cheney said they have turned the matter over to the Justice Department.
