Donald Trump was booed loudly by fans inside Madison Square Garden when he was shown on video screens during the national anthem prior to Game 3 of the NBA Finals. Trump was shown for about 10 seconds giving a military salute. The boos ended when the U.S. flag followed him on the screens, and fans cheered when New York Knicks players were shown. Trump is watching from Knicks owner James Dolan's suite. His presence Monday led to enhanced security measures, the cancelation of a watch party outside the arena and a no-bag policy for ticket-holders. The president told reporters later that he heard “mostly cheers.”
