The U.S. Open crowd booed Donald Trump when he arrived at the stadium and during the national anthem, which could be heard on the national telecast
A chorus of boos and sparse clapping greeted Donald Trump when the president arrived at the U.S. Open men’s final at Arthur Ashe Stadium in New York City on Sunday. Later, the boos continued and could be heard on the national telecast during the national anthem. The crowd booed again when the president was shown on an arena screen during a set break.
This is the second time Trump was heckled at the Open. The last time he attended the tournament in 2015, when he was a candidate for president, the crowd loudly booed him then, too.
