In an interview with CNN, Twitter co-founder and Medium CEO Ev Williams talks about Trump’s use of the platform and says traditional media, not just Twitter, is to blame for amplifying “the worst of Trump.

“What Trump has done with Twitter is pretty genius, frankly,” Williams said. “He’s a master of the platform like few others.”

“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.”
