U.S. government shutdown: A guide to what’s still open and who’s affected

The U.S. government has shut down after Congress failed to pass funding legislation.

Roughly 750,000 federal employees could be furloughed each day, though essential workers like TSA agents, air traffic controllers, and certain medical staff will continue working.

Social Security payments will continue, and critical services from the Department of Veterans Affairs, the CDC, and NOAA will operate, but many research and inspection activities will be paused.

National parks remain open, though with limited staff, and the shutdown may affect food safety and public services.
