Canadian hockey fans travel to U.S. with mixed feelings to support NHL teams

Trump’s rhetoric about annexing Canada, and the severe tariffs he has levied against the country, has sparked booing of 'The Star-Spangled Banner' in arenas and stadiums across Canadian professional sports. Wayne Gretzky’s ties to Trump have also stirred debate over The Great One’s loyalty to Canada. American fans have responded with occasional jeers during 'O Canada,' including a small portion of the crowd at Game 1 of the Canadiens-Capitals series.
