Rep. Devin Nunes (R-Calif.) will make a run for Republican Conference Chairman, a post that Rep. Adam Putnam (R-Fla.) announced late Tuesday that he would not seek again.

Nunes, an ally to House Minority Leader John Boehner (R-Ohio), has “spoken to a number of Members who are actually encouraging him to run for the position,” spokesman Andrew House said.

Nunes is the latest to enter an increasingly crowded race to succeed Putnam. Others candidates include Reps. Jeb Hensarling (Texas) and Mike Pence (Ind.), and possibly Reps. Mike Rogers (Mich.) and Dan Lungren (Calif.).

House said Nunes is currently just talking to Members and letting people know that he is interested in the Conference post.
