Homeland Security gives TSA workers authority to enforce Biden's mask mandate

Washington (CNN) The Department of Homeland Security said Sunday that Transportation Security Administration workers now have the authority to enforce President Joe Biden's transportation mask mandate "at TSA screening checkpoints and throughout the commercial and public transportation system."

Acting Secretary David Pekoske on Sunday signed a Determination of National Emergency , which said the TSA can "take actions consistent with the authorities" of its federal jurisdiction so it can enforce the mask mandate order laid out by the US Centers for Disease Control and Prevention late Friday.

"This includes supporting the CDC in the enforcement of any orders or other requirements necessary to protect the transportation system, including passengers and employees, from Covid-19 and to mitigate the spread of Covid-19 through the transportation system, to the extent appropriate and consistent with applicable law," Pekoske wrote.

The CDC order issued last week requires people to wear a mask while using any form of public transportation, including on board planes, trains, buses, boats, subways, taxis and ride-shares, as well as inside airports and other transportation hubs. The order goes into effect Monday at 11:59 p.m.

The TSA said in a news release Sunday that passengers without a mask "may be denied entry, boarding, or continued transport" and that failure to comply with the mask requirement can result in civil penalties.
