US President Donald Trump attended Madison Square Garden for Game 3 of the NBA Finals on Monday to cheer on his hometown team — but many of his fellow fans didn’t appear thrilled to have him there.

Axar.az informs, citing NBC News, as Trump was shown on the jumbotron here during the national anthem, the crowd erupted in loud booing. Trump smiled as he saluted through the song.

Trump was standing in Knicks owner Jim Dolan’s box, accompanied by a slew of administration officials, who included Transportation Secretary Sean Duffy, Interior Secretary Doug Burgum, White House deputy chief of staff Dan Scavino and Environmental Protection Agency Administrator Lee Zeldin.

Some of Trump’s family members, including special envoy Jared Kushner and granddaughter Kai Trump, also joined.

Trump’s presence at Monday’s game made him the first sitting president to attend an NBA Finals game. But he is no stranger to attending high-profile sporting events.
