World Cup watchers loudly boo US during National Anthem

World Cup audiences showed their anger with the United States by booing renditions of the Star-Spangled Banner.

Canadian spectators at a watch party jeered nonstop during the U.S. National Anthem at the opening of the U.S. versus Paraguay match in Los Angeles, according to a social media video.

Those boos followed heckling and hissing as the U.S. flag came out during the opening ceremony of the Canada versus Bosnia match in Toronto earlier in the day, per more video.

Trump was notably booed during his appearance at Madison Square Garden when the Knicks played the Spurs during Game 3 of the NBA Finals.
