R.F.K. Jr. Claims Censorship After Facebook and Instagram Briefly Block New Ad

Robert F. Kennedy Jr. has made censorship — specifically, claims that the government, news media and tech platforms have tried to stifle his message — a cornerstone of his independent presidential campaign.

This weekend, Mr. Kennedy got more fodder for his argument when Facebook and Instagram blocked a link to a new, sleekly produced 30-minute ad supporting his candidacy. The link appeared to have been blocked from Friday late afternoon until Saturday around midday.

Meta, which owns both platforms, called the episode a mistake. Andy Stone, a spokesman for Meta, said the link had been incorrectly flagged as spam. “It was mistakenly blocked, and it was corrected within a few hours” after the issue was discovered, Mr. Stone said.
