In the "well it is about time" category, see this from the Department of Homeland Security:
"Acting Secretary Pekoske Directs Today the Acting Secretary of Homeland Security announced the issuance of a National Emergency Determination to mitigate the spread of COVID-19. This determination enables TSA to implement President Biden’s Executive Order on Promoting COVID-19 Safety in Domestic and International Travel. TSA will require individuals to wear a mask at TSA screening checkpoints and throughout the commercial and public transportation system. Imposing these proven public health measures to reduce the spread of COVID-19 will mitigate the safety and security threat COVID-19 poses to transportation and contribute to the overall national effort to reduce the transmission of the disease."
