Facebook and Twitter took action against a post from President Trump Tuesday that claimed that COVID-19 is “far less lethal” than the flu. Trump made the tweet and posted the same message to Facebook just hours after arriving back at the White House following a multi-day stay at Walter Reed medical center, where the president was treated after testing positive for COVID-19.

Facebook took down Trump’s post outright Tuesday, stating that it “[removes] incorrect information about the severity of COVID-19, and have now removed this post.” Twitter hid the tweet behind a warning saying that it broke the platform’s rules about spreading misleading or harmful COVID-19 misinformation.
