"Anyone who is saying that the election is going to be fraudulent, I think that's problematic and I think additional context needs to be added to that," Zuckerberg told CBS This Morning co-anchor Gayle King. "This will definitely apply to the president. Once this policy goes into place, it will apply to everyone equally."
Facebook will also remove posts with "implicit misrepresentations" about how or when to vote, Zuckerberg said in a post on the social network, as well as posts that claim people will getif they take part in voting.
