A Russian mixed martial arts fighter with ties to President Trump, attorney Michael Cohen and Russian leader Vladimir Putin was questioned by the FBI last week, according to a report on Sunday.

Agents questioned Fedor Emelianenko , 41, in his hotel room before his MMA heavyweight bout against Frank Mir in Illinois, the brawler’s agent told the Associated Press.

“The FBI came to the hotel looking to talk to Fedor and they were very nice, came in to speak with Fedor for a few minutes, spoke to me, very cool guys, and that’s all I can really say about it. Again, the FBI did come to the hotel, they found us, knocked on the door,” Jerry Millen told the wire service.

“Hundred percent, kind of surprised,” he added . “They were very nice, very professional.”

​

The G-men also stuck around to watch Emelianenko’s contest with Mir on Saturday.

​

The fighter’s connection to Trump goes back to 2008 when he was signed by Affliction Entertainment, a fight league Trump had an ownership stake in, the AP reported.

​

Cohen, Trump’s longtime confidant and personal lawyer, was the league’s chief operating officer. And Putin has attended Emelianenko’s fights and has been photographed with him.

​​

Affliction folded for financial reasons in 2009 after two events, both headlined by Emelianenko.

​

FBI agents raided Cohen’s office, home and hotel room two weeks ago looking for information about a nondisclosure agreement he worked out with porn star Stormy Daniels, who alleged she had a sexual affair with Trump in 2006.

​

Cohen paid her $130,000 as part of the deal less than two weeks before the 2016 election.

​

The investigation into Cohen’s dealing with Daniels, whose real name is Stephanie Clifford, is linked to special counsel Robert Mueller’s probe into Russian meddling in the 2016 election.
