Toronto (CNN Business) President Donald Trump is a "master" of Twitter, according to the company's co-founder Ev Williams.

"What Trump has done with Twitter is pretty genius, frankly," Williams said in an interview with CNN Business at the Collision tech conference in Toronto on Tuesday. "He's a master of the platform like few others."

The president regularly uses his Twitter account to go after his political opponents and has made false and misleading statements on the platform. But Williams argued the potential negative effects of the president's tweets on the country's political discourse are "trivial compared to the effect of the broader media."

"The vast majority of the electorate is not on Twitter reading Trump's tweets and being convinced by that," said Williams. "What they're convinced much more by is the destructive power of Fox News, which is much, much more powerful and much more destructive than Twitter."

A Fox News spokesperson did not respond to a request for comment Wednesday morning.
