USA men's ice hockey player Brady Tkachuk has distanced himself from an AI-enhanced White House video in which he appears to disparage Canadians, saying "those words would never come out of my mouth".

The video was published on the official White House TikTok account after the US beat Canada on Sunday to win gold at the Winter Olympics and is marked as using artificial intelligence.

It features a modified clip of Tkachuk speaking at a news conference for last year's 4 Nations Face-Off, during which Canadians booed the US national anthem.

Tkachuk appears to say: "They booed our national anthem, so I had to come out and teach those maple-syrup-eating [expletive] a lesson. Canada, we own you little bro."
