Representative Kevin McCarthy, the minority leader, on Sunday officially endorsed Representative Elise Stefanik in her bid to oust the No. 3 House Republican, Representative Liz Cheney, who has hemorrhaged support over her repudiation of former President Donald J. Trump’s lies about election fraud.
“Yes, I do,” Mr. McCarthy told the Fox News host Maria Bartiromo when she asked whether he supported Ms. Stefanik’s push to become the Republican conference chairwoman.
“We need to be united, and that starts with leadership,” Mr. McCarthy said. “That’s why we will have a vote next week.”
