CNN chief Jeff Zucker says Facebook’s policy not to monitor political ads for truth-telling is ludicrous and advised the social media giant to sit out the 2020 election until it can figure out something better.

Zucker, in an appearance at a conference sponsored by his own network, also derided rival Fox News as “conspiracy TV” and expressed interest in hiring its former news anchor, Shepard Smith, who left earlier this month.

CNN recently rejected two ads that President Donald Trump’s campaign sought to air, saying they repeated allegations against former Vice President Joe Biden that had been proven false.

Facebook ran the ad, however. The company has said that politicians have the right to free speech on its platform and that it’s up to citizens to investigate claims.

Zucker called the policy “absolutely ludicrous” and that Facebook should be called out on it. Many Democrats have also criticized the social media giant, which was a potent force in the last presidential election and a target of Russians who tried to influence the outcome through fake accounts.

“Given what happened in 2016, maybe they should just sit it out and not take any political ads until they figure it out,” he said.
