"I think she's got real problems," McCarthy told Fox & Friends host Steve Doocy while off the air before his Tuesday morning interview moments later, according to Axios. "I've had it with her. You know, I've lost confidence. ... Well, someone just has to bring a motion, but I assume that will probably take place."
During the interview, the California Republican said members of his caucus are "concerned" about her ability to "carry out the message," given her feud with former President Donald Trump.
"I have heard from members concerned about her ability to carry out the job as conference chair, to carry out the message," McCarthy said. "We all need to be working as one if we're able to win the majority. Remember, majorities are not given. They are earned."
Cheney has been on thin ice within the Republican Caucus since she became one of the 10 House Republicans who voted to impeach Trump for his role in the Capitol riot.
"This is about whether the Republican Party is going to perpetuate lies about the 2020 election and attempt to whitewash what happened on Jan. 6. Liz will not do that," Jeremy Adler, a Cheney spokesman, told the Washington Examiner in response to McCarthy's interview. "That is the issue."
Cheney and Trump's sparring has created waves in recent days.
On Monday, the former president tried to reclaim the phrase, "The Big Lie," a line many Trump critics have used to dub the fallout of the unproven, post-presidential election conspiracy theories and legal challenges, but she quickly pushed back.
"The Fraudulent Presidential Election of 2020 will be, from this day forth, known as THE BIG LIE!" Trump said on Monday. Less than an hour later, Cheney responded, "The 2020 presidential election was not stolen. Anyone who claims it was is spreading THE BIG LIE, turning their back on the rule of law, and poisoning our democratic system."
Cheney defeated the attempt to oust her from leadership in February.
McCarthy's office didn't immediately respond to a request for comment.
