House Freedom Caucus chairman calls for Cheney's resignation over support of Trump impeachment

House Freedom Caucus Chairman Rep. Andy Biggs is calling on Rep.Liz Cheney, a leader of the chamber's Republican conference, to resign from her post over her support to impeach President Trump.

"She should resign her position as a conference chair and should not be serving this conference. That's it," Biggs told the Washington Examiner onTuesday evening.

As the House voted Tuesday evening to ask that Vice President Mike Pence invoke the 25th amendment, Cheney, the House Republican Conference chairwoman, the third-highest post among House Republicans, released a statement making clear her intentions to support the impeachment. 

"Much more will become clear in the coming days and weeks, but what we know now is enough, the Wyoming congresswoman wrote. "The president of the United States summoned this mob, and lit the flame of this attack. Everything that followed was his doing. ... There has never been a greater betrayal by a President of the United States of his office and his oath to the Constitution."

Four other GOP congressmen have said they will support impeachment efforts: New York Reps. John Katko New York; Adam Kinzinger, of Illinois; Fred Upton, of Michigan; and Jaime Herrera Beutler, of Washington.

Biggs, of Wyoming, whose caucus includes some of the most conservative members of the House, said he would not support impeachment, nor would he support censuring the president, which has arisen as a possibility this week.
