Rep. James Comer (R-KY) worried on Sunday that one or two moderate Republicans could derail his entire effort to impeach President Joe Biden.

During an interview on Fox News, host Maria Bartiromo asked Comer if Republicans could pass an authorization for an impeachment inquiry after losing former Rep. George Santos (R-NY).

"Do you feel that you have the votes within the House right now to get a formal impeachment inquiry?" she wondered.

"I do," he replied. "A great thing happened during Thanksgiving. The members went home, many of them for the first time, and circulated for the first time in over ten weeks. And they met people in Walmart and people on Main Street."

Comer suggested Republicans were more ready than ever to impeach Biden.

"So I'm confident we're going to have the votes to move forward with this impeachment inquiry," he said.

"And you've got to have a near majority," Bartiromo noted. "The majority is so slim, even less now with George Santos being expelled this week, right?"

"Yeah, it's tough," Comer agreed. "I think we could lose one or two members. I mean, Ken Buck, he votes no on everything. He's certainly doing everything he can to try out to be the next anchor for MSNBC."

"At the end of the day, I think our members realize that this is of the utmost importance," he insisted.
