The chief of advertising integrity at Facebook Rob Leathern has left the social media giant,Reuters reported.

Leathern had informed the Facebook management earlier last month about his decision to quit the company on Facebook’s internal network.

Leathern said in the post that he was "leaving Facebook to work on consumer privacy beyond just ads and social media," without disclosing where he was headed.

Leathern was often the public face of the company’s controversial political advertising policies. Prior to the November 3 election, Facebook was heavily criticized for allowing misleading claims and conspiracy theories to spread widely on its platforms.

In November, Leathern had tweeted that Facebook did not have "the technical ability in the short term to enable political ads by state or by advertiser."

Facebook lifted a temporary post-election ban on political ads in Georgia ahead of the January 5 runoff that will determine which party controls the US Senate.
