Trump has grown angry at Mark Levin, a sign of a growing rift inside his own media circle.

• Trump has fully soured on the conservative host Mark Levin after once being close to him.
• He now regrets listening to Levin, comparing it to a bad relationship he can't believe he was ever in.
• His anger reaches beyond Levin to the wider group of allies who pushed him toward a decision he now regrets.
• The falling-out points to tension among the right-wing voices who shape Trump's thinking.

Outlook: Expect more public friction between Trump and the pundits who once had his ear.
