President Trump was welcomed into Madison Square Garden on Saturday night with heavy booing from the crowd.
Trump, who was also met with some cheers, was at the arena to watch the main fight of UFC 244.
It was the second time in six days the president has been heavily booed during a public appearance.
Last Sunday, Trump was in attendance for Game 5 of the World Series in Washington. When he was recognized on the scoreboard, he was met with loud rejection.
In addition to the boos inside MSG, protestors gathered outside the arena prior to his arrival.
