Canadian fans boo US anthem as tariffs spur 'buy local' pledge

A few hours after President Donald Trump announced that he would impose steep tariffs on Canada, hockey fans in the capital Ottawa booed the Star-Spangled Banner during a National Hockey League game against a visiting US team.

On Sunday, during a National Basketball Association game between the Toronto Raptors and the Los Angeles Clippers, it happened again, continuing throughout the song and almost drowning out the 15-year-old singer's arena performance.
