President Donald Trump became the first sitting president to attend an NBA Finals game, creating a unique atmosphere Monday night.

Fans warned that the president's game day plans could deflate the Knicks' momentum as the team heads home with a 2-0 lead over the Spurs.

Trump is making a rare trip back to New York City as president to cheer for them in Game 3 of the NBA Finals against the San Antonio Spurs on Monday night.
