Twitter co-founder Ev Williams on Tuesday claimed Fox News is "much more destructive than Twitter."

CNN Business interviewed Williams, who now runs online publishing platform Medium, at the Collision tech conference in Toronto. Williams was asked about President Donald Trump's impact on the social media platform and how media companies are impacted by social media.

In addition to calling Trump a "master of the platform like few others," he took a swipe at Fox News by saying it is more damaging to discourse than Trump's tweets.

"The vast majority of the electorate is not on Twitter reading Trump's tweets and being convinced by that," Williams told CNN Business. "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."

CNN Business's Donie O'Sullivan reported that many people in the Silicon Valley "believe traditional media outlets have devoted extensive coverage to the destructive effects of big tech companies while not examining their own role in creating a more polarized society."

"Why the media's not critiquing itself I think is kind of obvious, and it's very easy to blame the tech platforms," Williams said. "But it's an ecosystem and the traditional media companies that have benefited financially from Trump very much outweigh the tech companies."

Williams's viewpoint of Fox News is not surprising. Twitter CEO Jack Dorsey admitted last summer the platform has left-leaning bias.

"We need to constantly show that we are not adding our own bias, which I fully admit is left, is more left-leaning," Dorsey said. "I think it's important to articulate our bias and to share it with people so that people understand us, but we need to remove all bias from how we act and our policies and our enforcement."
