Donald Trump is pushing for Mitt Romney’s niece to be the next GOP boss.

Ronna Romney McDaniel, the chair of the Michigan Republican Party, is being rewarded with the heavyweight endorsement for her part in delivering the state to the billionaire on Election Day, according to the Associated Press.

McDaniel will still need to be approved by Republican National Committee members, who will vote on Reince Priebus’ replacement early next year. Priebus is leaving the RNC to become White House chief of staff.

But the endorsement of Trump — now the most prominent Republican — is key to being selected party chair.

Prior to this year’s election, Michigan had not gone for a Republican presidential candidate in 28 years.

At a rally last Friday in Grand Rapids, Trump cheered the state chair for their success.

“Ronna McDaniel, what a great job you and your people have done!” Trump said at the victory rally.

“I was very impressed with you. She didn’t sleep for six months!” he added.

Trump passed on McDaniel’s uncle as secretary a state, a post the former Massachusetts governor coveted.

New Jersey Gov. Chris Christie, once a loyal supporter of Trump, had signaled his interest in becoming head of the RNC.
