Canadian speed skater and American snowboader face controversy at Olympics

Canadian Olympian Kim Boutin has shut down all of her social media accounts after receiving hundreds of angry Twitter messages following her controversial bronze-medal win in the 500-metre short-track speedskating race.

The Quebecer was bumped up from fourth place to third after a South Korean skater was disqualified for interference.

Also at the Olympics this morning, American snowboarding champ Shaun White dismissed as "gossip'' sexual-misconduct allegations made against him in a 2016 lawsuit filed by a former drummer in his band. 

Reporters' questions came hours after he won his third Olympic gold in the men's halfpipe.
