Twitter blocked a tweet from a contrarian medical adviser to President Donald Trump which stated that wearing masks does not help slow the spread of the coronavirus.
“Masks work? NO,” Scott Atlas said in a tweet removed as of Sunday by the social media site. The post, which linked to an article in the American Institute for Economic Research that argued against the effectiveness of masks, was in violation of the company’s rules against sharing false and harmful information, Twitter told CNN.
Trump regularly downplayed the effectiveness of masks until contracting the virus himself. Public health experts, including Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, have said wearing them helps slow the spread of the virus, which has killed nearly 220,000 Americans.
Atlas is a neuroradiologist with no epidemiology background affiliated with Stanford University’s conservative Hoover Institution. He has repeatedly argued that lockdowns are excessive, pushed for reopening the economy, and said it is preferable to expose young, healthy people to the virus so they develop immunity.
