Chad MayesAssembly Republicans announced new leadership on Thursday morning after weeks of tumult stemming from support from some caucus members for California's climate change policies.Assembyman Chad Mayes of Yucca Valley told lawmakers during a floor session that he will&nbsp;step down as caucus leader and that Assemblyman Brian Dahle&nbsp;of Bieber will succeed him&nbsp;before the end of the legislative session next month.&nbsp;Mayes&nbsp;has been&nbsp;trying to fend off challenges to his leadership&nbsp;after he supported extending the state's cap-and-trade program. He survived a vote on Monday, and another vote had been set for next Tuesday.However, Republicans caucused Thursday morning before the announcement."You&rsquo;re going to see a transition . . . to another leader who a lot of people respect," said Assemblyman Rocky Chavez of Oceanside.Dahle is one of four members of the caucus who have sought to replace Mayes at various points after July's cap-and-trade vote.UPDATES10 a.m. This article was updated with information about the Republicans' Thursday meeting.9:42 a.m. This article was updated to reflect comments made on the Assembly floor.9:15 a.m.: This article was updated with additional details about Assemblyman Chad Mayes.This article was originally published at 8:51 a.m.
