Yahoo Sports reports: Donald Trump is set to be the first sitting U.S. president to attend an NBA Finals game, bringing strict security measures that will require New York Knicks fans to navigate an extensive safety perimeter around Madison Square Garden and an expected lengthy wait to get inside the building. The security for Game 3 between the Knicks and San Antonio Spurs and the scene around the arena more closely resembled New Year's Eve in Times Square, and for fans, it might seem more akin to a trip to the airport. Trump’s appearance led the New York Police Department and Secret Service to establish a multi-block security perimeter around the arena, cancel a watch party outside and institute a no-bag policy for ticket-holders.
