Pat McAfee has apologized to Canada and hopes to move on after furiously reacting to the booing of the U.S. national anthem during WWE’s Elimination Chamber in Toronto. On Saturday night, WWE hosted its final premium live event before WrestleMania.

That’s been most apparent during professional sporting events that feature teams from both countries. Citizens from Canada have started booing the U.S. national anthem, and vice versa. It all seemingly got started at an NHL game last month (after President Trump initially announced the tariffs), and it’s continued into March.

Wrestling fans in Canada booed the Star Spangled Banner at the WWE’s Elimination Chamber event on Sunday — with commentator Pat McAfee calling Canada “terrible,” in a rant after the national diss, the NY Post reports.
