Rep. Lynn Westmoreland (R-Ga.) is pushing for a rules change requiring that anyone running for a new leadership post would have to resign their current leadership job. That would mean both McCarthy and Majority Whip Steve Scalise (R-La.) — who is vying to replace McCarthy in the No. 2 slot —would have to resign to run for their new leadership jobs…

Mulvaney, who has not decided who he’s backing in the Speaker’s race, posed one scenario that would likely keep House Parliamentarian Thomas J. Wickham Jr. extremely busy: McCarthy is nominated by the conference Thursday to be the next Speaker, and Scalise also becomes majority leader-elect; but McCarthy can’t close the deal and either Chaffetz or Webster is elected Speaker on a second ballot.

Who would the majority leader be at that point?

“I’ll bet you a dollar Kevin McCarthy thinks it’s him, and Steve Scalise thinks it’s him,” Mulvaney quipped.
