No one has ever said subtlety is Donald Trump’s strong suit.

“She’s the devil,” the GOP candidate said of his Democratic rival Hillary Clinton at a rally Monday night in Mechanicsburg, Pa.

The jab came as he chastised Sen. Bernie Sanders for conceding the Democratic primary race to Clinton and endorsing her.

“He should have not made a deal,” Trump told the packed gymnasium. “But he made a deal with the devil. She’s the devil. He made a deal with the devil.”

It wasn’t the first time Trump accused Sanders of dealing with the devil, but it was an escalation of the metaphor. A few days ago, Trump said Sanders “sold his soul to the devil.”

“We’re at a point where a presidential candidate can call his opponent “the devil” and people shrug it off and say “It’s a turn of phrase!” tweeted Sopan Deb, a producer for CBS News.
