Twitter announced Monday that it's suspending the account of Rep. Marjorie Taylor Greene (R-Ga.) for 12 hours.

Driving the news: "We took enforcement action on the account you referenced (@mtgreenee) for violations of the Twitter Rules, specifically the COVID-19 misleading information policy," Twitter said in an emailed statement.

A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.

Of note: The conservative Greene has been an outspoken critic of pandemic measures and apologized last month following outrage after she compared mask mandates in the House to the Holocaust.

  • She was removed from her committee assignments in February over her past endorsement of baseless conspiracy theories and violent rhetoric against Democrats.
  • Greene's suspension comes days after President Biden said social media platforms were "killing people" by allowing COVID-19 vaccine misinformation on their sites. He clarified earlier Monday that he meant those who post vaccine misinformation were to blame.

Context: Twitter announced in March it was escalating enforcement action on pandemic misinformation over repeated violations of its policy, including a 12-hour suspension.

  • This new policy saw Twitter suspend Greene's account without explanation for 12 hours that month. The company later said this was due to an automated technology error.

The big picture: Some conservative lawmakers, along with media figures, have complained that Big Tech companies intentionally censor their viewpoints and used this argument in their push for regulation.

  • However, a study in February found these claims to be "a form of disinformation."
  • Greene could not immediately be reached for comment on the Twitter suspension, which was first reported by the New York Times.

Editor's note: This article has been updated with new details throughout.

Biden clarifies vaccine comments: "Facebook isn't killing people"

President Biden attempted to clarify comments he made last week about Facebook, saying on Monday that the company itself is not "killing people" — but those who post misinformation about COVID-19 vaccines are.

Why it matters: The Biden administration has ratcheted up pressure on social media companies, especially Facebook, to increase their efforts to eliminate misinformation on vaccines and the virus from their platforms.

Vaccine misinformation "aided and abetted" by social media, Murthy says

Surgeon General Vivek Murthy said Sunday that COVID-19 vaccine misinformation is "aided and abetted" by social media platforms, further reinforcing the Biden administration's position.

Why it matters: Facebook and the White House have been engaging in an ongoing back-and-forth that was amplified Friday when President Biden said that social media platforms are "killing people" by allowing vaccine misinformation on their sites.

British Prime Minister Boris Johnson will isolate after being exposed to COVID-19, following backlash after he previously said he wouldn't, Reuters reports.

Why it matters: The prime minister's announcement comes just a day after Health Secretary Sajid Javid said via Twitter that he had tested positive for coronavirus following a meeting with Johnson.
