Republican Representative Liz Cheney faces opposition from within her own party Wednesday, as party leaders are lining up behind her possible replacement on House leadership.

Former President Donald Trump was the latest to show support for New York Representative Elise Stefanik, posting on his website his "complete and total endorsement" of her.

Cheney is third-ranking in the Republican leadership in the House. Second-ranking House GOP leader Steve Scalise also backed Stefanik earlier in the day.

Calls for Cheney's removal have grown after her criticism of former President Trump. She blamed him for the Capitol riots and voted to impeach him.

On Wednesday, Cheney wrote an Op-Ed for the Washington Post, in which she said that the Republican Party is "at a turning point" and they must choose if they want "truth and fidelity to the Constitution."

She also asked that her fellow Republicans support the ongoing investigation by the Justice Department into the riot at the U.S. Capitol on Jan. 6, as well as a separate, bipartisan congressional commission into the event.

News of the op-ed comes as a secret ballot vote among House Republicans to replace Cheney could come as early as next week.
