Former “Late Show” host David Letterman on Monday told GQ he’s “disappointed” that Donald Trump is representing the United States, adding, “it makes me sick.”

“I'm disappointed that this man is representing me and my country. It makes me sick,” Letterman told the men’s magazine.

Despite this, Letterman said he has “no reason to regret” having Trump on his show. “He was a great guest. He was just a big, wealthy dope who'd come on and we would make fun of his hair. I would refer to him as a slumlord. But now, this goon... I don't know.”

“He’s demonstrated himself to be a man without a core, a man without a soul,” Letterman said. “Is there a guy in there?”

Letterman noted he would “love to have 90 minutes with [Trump] in a TV studio,” adding he would ask the president, “All right, Don: What the fu*ck happened?”
