U.S. government faces potential shutdown on Oct 1 if Congress fails to agree on spending.

The U.S. government faces a potential shutdown on October 1 if Congress can't agree on spending. Essential services like the U.S. Postal Service and Social Security will continue, while many federal employees may face furloughs. Law enforcement, including the FBI and Secret Service, will remain operational. However, national parks and many federal programs, including some public health initiatives, could close or face delays. The shutdown's length depends on Congress's resolution.
