As Republicans struggled for a second day to elect a House speaker, Rep. Byron Donalds of Florida emerged as the choice of conservative holdouts who are refusing to support Kevin McCarthy’s bid.

CNNWASHINGTON (CNN) - Florida Republican Rep. Francis Rooney said Saturday he would not run for reelection, after suggesting he could be open to impeaching President Donald Trump. "I've done what I came to do," Rooney told Fox News. The congressman said he wanted to be a "model for term limits," and added: "People need to realize ... this is public service not public life." His statement was a striking one among House Republicans defensive of Trump. The congressman said Mick Mulvaney, the acting White House chief of staff, confirmed Thursday what Trump had denied -- that the President engaged in a quid pro quo with Ukraine.
