Twitter has removed a tweet from White House coronavirus task force member Dr. Scott Atlas that sought to undermine the importance of face masks because it was in violation of the platform’s Covid-19 Misleading Information Policy, a spokesman for the company confirmed on Sunday.

Atlas wrote in a tweet posted Saturday, “Masks work? NO” followed by a series of misrepresentations about the science behind the effectiveness of masks in combating the pandemic.
