Justin Trudeau Does The ALS Ice Bucket Challenge (VIDEO)

Liberal Leader Justin Trudeau has enlisted some unlikely helpers to take on the ALS Ice Bucket Challenge.

In a video posted to the Liberal Part of Canada's YouTube channel, his wife Sophie and two of his children sit on a slide above him as they pour the ice-cold water on his head. Trudeau says that he's doing the challenge in memory of a friend that died from ALS.
