House Speaker Nancy Pelosi, in a statement following House Republicans' removal of Cheney as GOP conference chair by a voice vote, called out to "reasonable Republicans across the country" to "take back their party."

"Congresswoman Liz Cheney is a leader of great courage, patriotism and integrity. Today, House Republicans declared that those values are unwelcome in the Republican party," she said. "The Republican denial of the truth presented by Congresswoman Cheney is reflected in their denial of the need to seek the truth in a January 6th commission and to repair the damage of January 6th with a security supplemental immediately."

House Minority Leader Kevin McCarthy did not speak after the vote concluded behind closed doors.

Senate Minority Leader Mitch McConnell, asked by reporters for his reaction to Cheney's ouster and what it means for the future of the GOP, did not answer.

He made no mention of the then just-completed House Republican conference vote to boot Cheney from leadership in his Senate floor speech Wednesday morning, either.

While McConnell publicly defended Cheney in February, when she first faced a challenge in the wake of voting to impeach the former president, he has stayed silent on her fate this time around.

Sen. Dick Durbin, D-Ill., following the vote to remove Cheney from her leadership posted told Capitol Hill reporters it's a "sad day for the American Republican Party."

"It was an act of pure cowardice for them to remove her from leadership, and then to do it by a secret voice vote. That just tells the whole story as far as I am concerned," he said. "Donald Trump owns the soul of the Republican Party of America, and it was proved today in the House Representatives."

Senate Majority Leader Chuck Schumer said the House GOP has reached "a new and very dangerous low point" in ousting the Wyoming representative from leadership.

Republican Sen. Mitt Romney of Utah, another enemy of the former president like Cheney, on Tuesday warned in a tweet, "Expelling Liz Cheney from leadership won’t gain the GOP one additional voter, but it will cost us quite a few."
