It wasn't long after Rep. Anthony Gonzalez (R-Ohio) voted to impeach Donald Trump in January when the Republican congressman picked up a primary rival. Max Miller, a former Trump White House aide, kicked off his intra-party challenge in February.

Miller's former boss, Donald Trump, not only supports the Ohioan's campaign, the former president also held a fundraiser for his former staffer this week at Trump's West Palm Beach golf club.

But before Wednesday night's event, Trump summoned Ohio's four leading Republican U.S. Senate candidates to a backroom meeting. Politico reported overnight that the gathering was "a scene right out of 'The Apprentice.'"
