Trump Likely to Back Ronna Romney McDaniel for RNC Chair

— -- Ronna Romney McDaniel, the Michigan GOP Chairwoman, is likely to be Donald Trump's choice to be the chair of the Republican National Committee, senior transition sources told ABC News. Romney McDaniel is a niece of Mitt Romney, the former Republican nominee who was in the running to be Trump's secretary of state.

Trump's support will almost surely clear the path for Romney McDaniel, but she still has to run for the position. A decision will be made by the RNC's 168-member executive committee in January.

Romney McDaniel was long-favored for the position, with sources telling ABC News that she engendered strong support among her fellow RNC members and was a favorite of RNC Chair Reince Priebus, who has been tapped to be Trump's chief of staff.

Romney McDaniel appeared at Trump's rally on Friday in Grand Rapids, Mich. She became a public backer of Trump's after he won the Michigan primary, urging Michigan Republicans to unite around him after he clinched the Republican nomination.
