Twitter suspended Rep. Marjorie Taylor Greene, R-Ga., for 12 hours Sunday, saying she has repeatedly run afoul of the company’s misinformation policy.

Greene’s most recent posts included one that made false claimes about widespread voter fraud in Georgia in both the November election and in the Jan. 5 Senate runoffs, as well as a series of tweets that repeated more debunked claims and called Georgia’s elections officials “morons.”

Twitter restricted those posts from further promotion and slapped them with warning labels. Greene’s account remained live, but she is unable to post. After the riot at the Capitol this month, Twitter has ramped up its crackdown on misleading and false information.

Twitter’s civic integrity policy states that the company “will label or remove false or misleading information intended to undermine public confidence in an election or other civic process.”
