Twitter suspended Rep. Marjorie Taylor Greene, R-Ga., for 12 hours on Sunday, saying that she has repeatedly run afoul of the company's misinformation policy.
"The account referenced has been temporarily locked out for multiple violations of our civic integrity policy," a Twitter spokesperson said.
Following the riot at the Capitol earlier this month, Twitter has ramped up its crackdown on misleading and false information on its platform.
Twitter's civic integrity policy states the company "will label or remove false or misleading information intended to undermine public confidence in an election or other civic process."
A freshman lawmaker and a vocal supporter of Trump's efforts to overturn the election, Greene has previously expressed sympathy for QAnon, though she has since sought to distance herself.
