The Republican lawmaker from Georgia cannot tweet for 12 hours, after the White House criticized social media sites for amplifying vaccine lies.
SAN FRANCISCO — Twitter said on Monday that it was suspending Representative Marjorie Taylor Greene from its service for 12 hours after she posted messages that violated its policy against sharing misleading information about the coronavirus.
Ms. Greene, a Republican of Georgia, has been an outspoken opponent of vaccines and masks as tools to curb the pandemic. In tweets on Sunday and Monday, she argued that Covid-19 was not dangerous for people under the age of 65 who are not obese, and said vaccines should not be required.
But cases of the coronavirus are on the rise, and the highly contagious Delta variant accounts for more than half of new infections in the United States, federal health officials said this month. In Ms. Greene’s home state, Georgia, new cases have increased 193 percent in the past two weeks.
Twitter said Ms. Greene’s tweets were misinformation, and it barred her from the service until Tuesday. “We took enforcement action on the account @mtgreenee for violations of the Twitter Rules, specifically the Covid-19 misleading information policy,” a Twitter spokesman said. The company also added labels to Ms. Greene’s posts about the vaccines, calling them “misleading” and pointing to information about the safety of the inoculations.
