“He’s an old friend ... but some of his opinions have gone," King said of Trump, the presumptive GOP presidential nominee, during an interview with SiriusXM's Pete Dominick on Thursday.

ADVERTISEMENT "I like him," King continued, saying he doesn't consider Trump to be a "racist" but disagrees with the controversial businessman on "keeping people out of the country, building a wall — I don't like walls."

"I don't know yet. I have this Jewish sense of loyalty," the longtime TV and radio host said of whether he'll vote for Trump, noting he's interviewed the billionaire repeatedly and has known him for three decades.

"I know Hillary well too ... I’ll vote for Hillary, probably," King said.

King suggested Trump didn't believe in some of the positions he's advocated in his GOP White House bid.

"You know he's not anti-abortion," King said, adding, "How can he not believe in climate change?"
