United States President Donald Trump was met with loud boos from sections of the crowd as he attended Game 3 of the NBA Finals at Madison Square Garden in New York on Monday, becoming the first sitting US president to attend an NBA Finals game.
The reaction came when Trump appeared on the arena's giant screens during the national anthem, where he was shown saluting the US flag.
The New York Knicks were defeated 115-111 by the San Antonio Spurs, reducing their lead in the best-of-seven series to 2-1.
After the game, Trump downplayed the crowd's response, telling reporters: "It was, I think, mostly cheers. It was loud, and it was very enthusiastic."
Trump's appearance prompted an extensive security operation around Madison Square Garden.
Thousands of New York Police Department officers and hundreds of Secret Service personnel were deployed, while airport-style screening procedures were introduced for ticket holders.
Authorities established multiple checkpoints, restricted pedestrian and vehicle access around the arena, and installed barriers and fencing near the venue.
A specially constructed suite featuring bulletproof glass was prepared for the president.
The Secret Service also deployed counter-drone technology as part of its security arrangements.
Officials urged fans to arrive hours before tip-off due to expected delays, while watch parties traditionally held outside the arena were cancelled.
The heightened security measures generated frustration among some fans and local residents, with long queues forming outside the venue and nearby businesses reporting reduced foot traffic.
Protesters gathered along parts of Trump's route to the arena, displaying signs reading "Trump must go" and making gestures toward the presidential motorcade.
Some Democratic politicians also criticised the visit, arguing that the restrictions disrupted a major sporting event for New Yorkers.
However, reactions were not universally negative.
Several fans said they appreciated the president's attendance despite the inconvenience caused by the security operation.
NBA Commissioner Adam Silver welcomed Trump's presence, describing him as a genuine Knicks fan and emphasizing the unifying role sports can play.
The game drew a packed crowd despite high ticket prices, with celebrities, public officials and basketball fans filling the arena during the Knicks' first NBA Finals appearance since 1999.
