President Donald Trump arrived at Madison Square Garden for Game 3 of the NBA Finals Monday evening, the first sitting president to attend an NBA Finals game.

Trump is occupying a box at the arena with other administration officials, including White House Deputy Chief of Staff Dan Scavino, EPA Administrator Lee Zeldin, Interior Secretary Doug Burgum and Transportation Secretary Sean Duffy.

Seated with him as well are his son-in-law, Jared Kushner, and granddaughter, Kai Trump, as well as Special Envoy to the Middle East Steve Witkoff.

Chants of “USA! USA!” filled the arena just before the performance of “The Star-Spangled Banner,” but the New Yorkers in attendance booed the president when his image was caught on the in-arena Jumbotron during the singing of the anthem. Once the anthem was over, the audience took up a chant in favor of the Knicks, who are playing against the San Antonio Spurs.

New York City Mayor Zohran Mamdani is also in attendance, in a standing-room-only section that he is sharing with local lawmakers.
