A former aide for President Donald Trump said he’s refusing to comply with a subpoena from special counsel Robert Mueller and added it’d be humorous if Mueller tried to have him arrested.

Sam Nunberg, who advised Trump during the 2016 campaign, appeared on MSNBC after the Washington Post published a story saying he’d refuse to honor a subpoena to appear in front of a federal grand jury investigating Russia’s interference in the election. The Post said he provided a copy of what appeared to be a subpoena seeking documents related to Trump and others, including emails.

“ ‘I think it would be really, really funny if they wanted to arrest me.’ ” — Sam Nunberg, former Trump campaign aide

Nunberg, who was dismissed by Trump, said his arrest would be funny since he didn’t want to spend “80 hours going over emails I had with Steve Bannon and Roger Stone.” Bannon was formerly Trump’s White House strategist and Stone was an adviser.

Nunberg also raised hackles at the White House after he indicated the special counsel may have something on the president. “I think they may,” he said. “I think that he may have done something during the election. But I don’t know that for sure.”

Trump has repeatedly denied that there was collusion between his campaign and the Kremlin, and White House press secretary Sarah Sanders amplified that message.

“As we’ve said many times before, there was no collusion with the Trump campaign,” Sanders told reporters. “Anything further on what his actions are, he hasn’t worked at the White House so I certainly can’t speak to him or the lack of knowledge he clearly has.”

A former White House counsel said Nunberg is playing with legal fire.

“He will be held in criminal contempt for refusing to show up,” tweeted John Dean, President Richard Nixon’s counsel.

Asked later in a separate CNN interview about complying with the subpoena, Nunberg said, “Screw that. Why do I have to go? Why? For what?”
