Facebook is making changes to its advertising policies in the wake of an investigation that confirmed the company unknowingly sold ads to Kremlin-backed sources trying to sway the 2016 U.S. presidential election.

Facebook will hire 1,000 additional people to the internal team that reviews and removes Facebook ads, according to details shared via email with Recode by a Facebook spokesperson.
