It turns out that while President Donald Trump might be a big fan of mixed martial arts, many fight fans are not big fans of his: Trump was bathed in sustained boos, and some cheers, on Saturday night, when he attended an Ultimate Fighting Championship card at Madison Square Garden in New York.

Trump, who is facing at an impeachment inquiry by House Democrats, was joined at MSG by House GOP Leader Kevin McCarthy, North Carolina Rep. Mark Meadows, New York Rep. Peter King, and sons Donald Trump Jr. and Eric Trump.

A handful of signs reading “Remove Trump” and “Impeach Trump” dotted the crowd, according to several reports.

According to the New York Post:

Inside, Trump stood up in his seat in the VIP section and waved to a crowd that mostly cheered — though there were also plenty of “boos” and the occasional raised middle finger as well.

The jeers marked the second time in a week that Trump was booed in public. Baseball fans heckled him at Game 5 of the World Series in Washington, D.C., last Sunday, and fans at Nationals Park chanted, “Lock him up! when he was shown on the ballpark’s video screen.

On Saturday night, protesters gathered outside Madison Square Garden to support and resist the President, who stayed for the entire four-hour show. Protesters outside MSG chanted, “Danger, danger, there’s a Fascist in the White House,” over a bullhorn and held signs that read “Trump/Pence Out Now!” Once the fights started, there were no noticeable signs or sustained calls of support or protest for Trump.

The packed house at the Garden stood and fans had their phones out, craning their necks to catch a glimpse of the president as he took his cageside seat. Trump smiled and waved to fans as AC/DC’s “Back in Black” was blasted over the speakers shortly before the start of the 10 p.m. event. Trump received a mixed reaction.

Trump hugged boxing legend Roberto Duran as they posed for a picture and sat in the same row as UFC President Dana White. Trump’s relationship with White dates to UFC’s formative years before its rise into a billion dollar promotion.

New Jersey was one of the first states that embraced UFC, and White credits cards at the Trump Taj Mahal for helping the company grow. White spoke at Trump’s request at the Republican National Convention, and they are occasional dining partners.

Trump Jr. tweeted White told the family, “it was the most electrifying entrance he seen in 25 years of doing this.” The Trump brothers sat cageside in August in New Jersey in support of Trump fan Colby Covington.

In the UFC 244 main event, Jorge Masvidal defeated a bloodied Nate Diaz via TKO before the fourth round.
