What’s affected by a government shutdown? Here’s which departments close down

Lawmakers on Capitol Hill are on the clock to avoid a government shutdown after a bipartisan funding agreement fell through Wednesday.
President-elect Donald Trump and allies Elon Musk and Vivek Ramaswamy came out against the agreement, sending House Republicans back to the drawing board.
The current funding runs out at the end of the day Friday, when Congress had planned to adjourn for the holidays.
If another agreement is not passed, the government will have to reduce federal services, but not all services will stop completely. Here is the breakdown:

What are essential services? These functions will continue
Any federal agencies that provide "essential" services will continue to provide them. According to the bipartisan nonprofit Committee for a Responsible Federal Budget, examples of functions that have continued during previous shutdowns include:
Air traffic control
Law enforcement
Border protection
Power grid maintenance
Social security and Medicare payments
The U.S. Postal Service will not be impacted as it does not rely on Congress for funding.
