The video, which has been also posted by the campaign to Twitter and YouTube, accuses Biden of using his power as vice president to influence Ukraine in order to benefit his son, Hunter. There is no evidence of wrongdoing by Joe or Hunter Biden. CNN has refused to air the ad.
The Biden campaign responded to the Facebook letter by calling the decision “unacceptable.”
Campaign spokesman TJ Ducklo said in a statement that the spread of “objectively false information to influence public opinion poisons the public discourse and chips away at our democracy.”
“Whether it originates from the Kremlin or Trump Tower, these lies and conspiracy theories threaten to undermine the integrity of our elections in America,” Ducklo said. “It is unacceptable for any social media company to knowingly allow deliberately misleading material to corrupt its platform.”
When asked about the ad being placed on other social media platforms, the campaign would not rule out sending similar letters.
The Biden campaign’s original letter to Facebook — addressed to founder and CEO Mark Zuckerberg, COO Sheryl Sandberg and Facebook Public Policy Director, Global Elections Katie Harbath — told the social media company it is “on notice” for the “absolute falsity” of the claims in the campaign ad. The Biden campaign wrote that it expected Facebook to exercise its “legal right” to reject or demote attempts to buy advertisements from Trump, the Republican National Committee or anyone allied with the Trump campaign that “spread these lies.”
