He attended game 3 in New York of the NBA Finals between the New York Knicks and the San Antonio. Given that he has been booed whenever he shows up at sports events and is shown on the bog screen, at this game they showed him during the playing of the national anthem, no doubt thinking that people would not boo at that time.
No such luck.
Donald Trump was loudly booed when he was shown on the video screens at Madison Square Garden on Monday night before Game 3 of the NBA finals between the San Antonio Spurs and New York Knicks.
Trump was shown on the jumbotron while the Star-Spangled Banner was being sung before the game, and jeers and boos broke out around the arena. The president was shown for a little over eight seconds and held a salute the whole time with a smile on his face. A few seconds later, the video board showed Knicks players in line and the boos turned to cheers.
It did not help that because he chose to attend, that inconvenienced everyone else, no doubt annoying them further.
Hours before tipoff, fans encountered heightened security around Madison Square Garden. A 10-foot perimeter fence surrounded the arena, ticket holders were advised to arrive at least two hours early and the team implemented a strict no-bag policy.
By midday, dozens of fans were already queueing to pass through metal detectors manned by Secret Service agents to access the team store.
“He could have picked any other day. This night is for the fans,” said Joanne Cadden, 53, a Knicks supporter from the Bronx who has followed the team since the early 1990s. “You’re making people go away from the Garden. This wasn’t the time.”
Gesturing toward the fencing and checkpoints surrounding the arena, Cadden added: “This looks like prison.”
To add insult to injury, Trump was later shown asleep during the game.
Given the heavy security that surrounds the US president that causes major inconveniences, they really should not go anywhere unless absolutely necessary.

Another inconvenience is that Madison Square Garden was built where the old Pennsylvania (train) Station was. Amtrak passengers use the Moynihan building across the street, but the main part of the current Penn Station is basically the basement of Madison Square Garden and is still used by commuters riding on New Jersey Transit and the Long Island Rail Road. (I have no clue how bad that was and haven’t heard anything about it, so maybe Penn Station was outside the security perimeter.)
