Ex-Trump aide who called president an 'idiot' doubles down: 'He's a complete pain in the ass to work for'

Sam Nunberg, a former campaign adviser to Donald Trump, not only reiterated his concession that he "probably" called the president an "idiot" — he also doubled down on his insults while also, bizarrely, defending him.

MSNBC host Joy Ann Reid, in for Chris Hayes, came to her interview with Nunberg prepared with quotes from Michael Wolff's stunning tell-all book Fire and Fury: Inside the Trump White House.

Nunberg was quoted in Wolff's book saying, among other insults, that Trump is "an effing fool" — a quote Reid threw back into the former aide's face.

"It's not that he doesn't know what he doesn't know," Nunberg said. "It's that he knows what he doesn't know but he doesn't care."

Discussing the now-infamous anecdote where Nunberg tried to teach then-candidate Trump the constitution only to have him get bored by the Fourth Amendment, the former aide tried to blast Wolff's writing — but only ended up making the president look worse.

"[Trump] has a granular level of the Constitution," he said, claiming he was able to get through "gotcha" questions on the nation's founding document with the candidate.

When asked about his insults on the president's intelligence, the former adviser doubled down.

"I probably did call him an idiot," Nunberg said once again. "By the way, Joy, he's probably called me much worse."

"You're not the president of the United States, Sam," she retorted.

After a back-and-forth with Reid where he both disparaged Trump and Wolff while also claiming to not criticize them and, in some instances, praise them, Nunberg cut the host off to interject a telling statement.

"Joy, he's a complete pain in the ass to work for," the former aide said. "Joy, he's terrible to work for."
