Even though Bernie Sanders has insisted that he will work to ensure Donald Trump never becomes president, the presumptive Republican nominee said Wednesday that he knows what’s truly in the Vermont senator’s heart when it comes to Hillary Clinton.

Speaking to supporters in Bangor, Maine, Trump boasted about his political movement, remarking, “It’s bigger than Bernie Sanders,” in reference to the senator’s upstart campaign that gave Clinton’s a competitive run.

“And yet— I have to say one thing about Bernie — he, you know, he’ll be nasty and say, ‘Oh, I’d never vote for Trump,’ but that’s OK. I know what he thinks inside.” Trump said. “He hates her. He hates her.”

Trump continued, “I mean, he cannot stand her.”

“I’m pretty good with people,” the Manhattan businessman declared. “Bernie Sanders cannot stand Hillary Clinton.”
