WASHINGTON — Ted Nugent, Kid Rock and Sarah Palin had a fete to remember at the White House for several hours Wednesday night, as President Trump treated the high-profile supporters to a white-china private dinner, a room-by-room tour and free-range policy chat.

Mr. Nugent — a guitar demigod, knife-between-the-teeth hunter and conservative provocateur — offered an inside glimpse of a gracious, relaxed and house-proud president with ample time to offer his thoughts on a wide array of topics, from entertainment to existential geopolitical perils.

“We were there for four hours, man!” Mr. Nugent, a 68-year-old Detroit native, said in a telephone interview on Thursday, using a four-letter expletive to signal his amazement at Mr. Trump’s willingness to spend so much time with his three casually dressed visitors.

“He gave us a wonderful personal tour of every room and talked about the origins of every carpet and every painting — there was a Monet — and then we had dinner,” said Mr. Nugent, who has referred to former President Barack Obama as a “mongrel” and to Hillary Clinton with an array of unflattering epithets.
