Facebook Inc is temporarily banning a Republican political action committee, the Committee to Defend the President, from advertising after it repeatedly shared content that was deemed false by external fact-checkers, the social media company said on Thursday.

“As a result of the Committee to Defend the President’s repeated sharing of content determined by third-party fact-checkers to be false, they will not be permitted to advertise for a period of time on our platform,” Facebook spokesman Andy Stone said in a statement.
