Former Donald Trump campaign aide Sam Nunberg said Monday that his interaction with special counsel Robert Mueller's investigators made him feel that the president may have "done something" during the campaign.
Nunberg appeared on MSNBC for an unusual, free-wheeling interview with host Katy Tur following news that he would refuse to appear in front of Mueller's grand jury, saying, "Let him arrest me."
"I'm not going to go to jail," Nunberg said when asked by Tur if he thought he would be held in contempt for publicly snubbing the investigation into Russia's interference in the 2016 presidential election.
"What you're doing is surprising to say the least, but you sat there in that room being questioned by Mueller's investigators," Tur said. "I want to hear directly from you. Do you think that they have something on the president?"
"I think they may," Nunberg said. "I think that he may have done something during the election, but I don't know that for sure."
"Why do you think that?" Tur asked.
"I can't explain it unless you were in there," Nunberg responded.
"Explain the atmosphere," Tur said.
"The way they asked questions about anything I heard after I was fired from the campaign to the general election to even November 1, it insinuated to me that he may have done something," Nunberg said.
Later on CNN in a separate interview, Nunberg said the questions he received about Trump's "business dealings" were what made him suspicious.
The Trump campaign fired Nunberg on Aug. 2, 2015—less than two months after the campaign launched—because of past racially charged Facebook posts.
Nunberg forwarded the Washington Post a copy of the subpoena seeking documents related to Trump and nine other people, including exiting White House communications director Hope Hicks, former chief strategist Steve Bannon, adviser Roger Stone, ex-campaign manager Corey Lewandowski, and Trump attorney Michael Cohen.
He told Tur that the subpoena was "absolutely ridiculous," that it was a "joke" to think Trump colluded with the Russians, and that it would be "funny" if he was arrested. He also said his lawyer would likely "dump me."
"I'm not spending 80 hours going over my emails with Roger Stone and Steve Bannon and producing them," Nunberg told the Washington Post. "Donald Trump won this election on his own. He campaigned his ass off. And there is nobody who hates him more than me."
