Republican congresswoman Marjorie Taylor Greene’s Twitter account has been suspended for posting “misleading” information about Covid-19.
Twitter said Marjorie Taylor Greene’s account would be in “read-only mode” for 12 hours.
The Republican lawmaker has been an outspoken critic of vaccines and the use of masks.
Last month Marjorie Taylor Greene apologized for likening coronavirus mask rules to the treatment of Jews in Nazi Germany.
In two tweets on July 19, she argued that vaccines should not be required, and that Covid was not dangerous for people aged under 65 who are not obese.
Both posts are still on display, but have been tagged by Twitter as “misleading”.
Marjorie Taylor Greene was suspended from Twitter in April, but the company later rescinded the ban, saying it was a mistake caused by its automated moderation system.
In response to her latest suspension, Marjorie Taylor Greene said Silicon Valley companies were attacking free speech with support from the White House.
“These Big Tech companies are doing the bidding of the Biden regime to restrict our voices and prevent the spread of any message that isn’t state-approved,” she said in a statement to the New York Times.
Last week, President Joe Biden urged social media companies to take more action against the spread of false information about coronavirus and vaccines on their platforms.
“They’re killing people,” he told reporters.
“The only pandemic we have is among the unvaccinated.”
Health officials have warned the country’s current spike in Covid-19 deaths and infections is exclusively hitting unvaccinated communities.
Twitter has repeatedly banned users for sharing false information, and in March it introduced a new policy with penalties for users.
Under the new rules, 12-hour suspensions are given for second and third violations of its policy. A fourth breach results in a week-long ban, and a fifth leads to a full ban.
In January, Twitter permanently suspended President Donald Trump for posts that it said incited violence after the storming of the Capitol by hundreds of his supporters.
