House Republicans are looking for potential candidates for the next Speaker of the House besides Minority Leader Kevin McCarthy, R-Calif., in case he is unable to obtain enough support to win the post in the next Congress.

“If somebody were to come out now and we didn’t deliver enough votes to stop Mr. McCarthy, that there would be a real potential for blowback,” Rep. Andy Biggs, R-Ariz., told The Hill.

Biggs, the former chair of the House Freedom Caucus, has launched his own bid to become speaker, saying in a tweet that he’s running “to break the establishment,” and claiming that “Kevin McCarthy was created by, elevated by, and maintained by the establishment.”

Biggs added to the Hill on Monday, “They want to be very careful. So I think I think people are interested. They’ve expressed it to some of us … I think people are being wary.”
