“Morning Joe” host Joe Scarborough said on Friday that potential presidential contender Sen. Rand Paul (R-KY) did himself no favors with his combative media appearances this week.

“I was really surprised by how thin-skinned Rand Paul was,” Scarborough said on his morning show, referring to a week when Paul shushed a female CNBC journalist during an interview and then slammed the “liberal media” for reporting on his vaccination comments.

The MSNBC host suggested that Paul staffers take a hint from Ronald Reagan’s campaign team, which reportedly intervened after he lost his temper during an appearance in the mid-1960s.

“His entire campaign team surrounded him after he blew up and said, ‘If you do that again, we’re all leaving,'” Scarborough said. “Somebody needs to say that to Rand Paul.”

“He can’t afford too many more weeks like this or he becomes the Ross Perot of the Republican Party in 2016,” he added.
