Republican Congresswoman Marjorie Taylor Greene has been temporarily suspended by Twitter over “misleading” posts about COVID-19. The micro-blogging site said the Georgia representative’s account will be in “read-only mode” for a period of 12 hours.

The 47-year-old is an ardent critic of vaccines and the use of masks and issued an apology last month after comparing mask-wearing norms to the treatment of Jews by Nazi Germany, The BBC noted.

Greene posted two tweets on Monday, wherein she argued that the vaccines are not required as COVID was not a threat to people under the age of 65 and not obese.

In response, she said that “These Big Tech companies”, backed by Washington DC, were curbing free speech.

In a statement to The New York Times, she said, “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 was earlier suspended from Twitter in April, although the social media giants restored her account shortly, clarifying that the ban was a mistake, caused by an automated moderation system.

President Joe Biden has called for social media companies to ramp up action against misinformation surrounding COVID and vaccines on their platforms. “They’re killing people,” Biden said last week, adding, “The only pandemic we have is among the unvaccinated”.

American health officials have said that the current surge in cases and deaths is almost exclusively hitting unvaccinated communities.

Twitter has repeatedly banned users for misinformation, having introducing a new policy with penalty for users in March.

As per the new rules, a 12-hour ban is given for second and third offences and a fourth violation will result in a week-long suspension. The account will be banned if its policies are banned for a fifth time.

In January, the company permanently banned former president Donald Trump’s account for what it said were posts inciting violence after his supporters stormed the US Capitol.
