President Trump re-tweeted a mixed-martial arts fighter’s claim he’s a “bad motherf–ker” on Sunday — the morning after watching the pugilist’s bout at Madison Square Garden.

“Great fight Champ!” Trump wrote in the Sunday morning message, retweeting comments from fighter Jorge Masvidal after he defeated Nate Diaz in the octagon during UFC 244.

“No matter what your views on Trump as a president, the guy’s a bad motherf–ker, man — the money that he’s made, the obstacles that he’s conquered. he’s a bad motherf–ker in his own way,” Masvidal said.

The president traveled to New York on Saturday to attend the ultimate fighting match, where Masvidal bested Nate Diaz in the main event.

Trump was met with more cheers than boos when he arrived at MSG.

In another Tweet Sunday about the UFC contests, Trump likened it to a MAGA rally.

“Walking into Madison Square Garden last night with @danawhite for the big @UFC Championship fight was a little bit like walking into a Trump Rally. Plenty of MAGA & KAG present. Great energy. Fantastic job Dana!” Trump wrote, referring to UFC president Dana White Jr.

Trump watched the combat with House Minority Leader Kevin McCarthy, Rep. Peter King and his sons, Donald Jr. and Eric.

The president remained in New York overnight at Trump Tower.

The Queens-born commander in chief said last week that he will be switching his legal residency to Mar-a-Lago, his exclusive resort in South Florida.

“I love New York, but New York can never be great again under the current leadership of Governor Andrew Cuomo (the brother of Fredo), or Mayor Bill DeBlasio,” he wrote, citing high taxes, overzealous prosecutors and a dwindling population base.
