Toronto Mayor Rob Ford says a purported video of him smoking crack cocaine does not exist and he attacked the media again, calling the press a "bunch of maggots."

The mayor of Canada's largest city, speaking Sunday on the weekly radio show he hosts with his brother Doug Ford, a city council member, reiterated that the allegations are ridiculous, but he still has not said whether he has ever used crack.

The video has not been released publicly and its authenticity has not been verified. Reports on gossip website Gawker and in the Toronto Star claimed it was taken by men who said they had crack to Ford. The Associated Press hasn't seen the video.

The Star reported that two journalists had watched the video.
