Yes, the United States federal government did shut down on October 1, 2025, at 12:01 a.m. EDT due to Congress's failure to pass appropriations legislation for the 2026 fiscal year. This shutdown is a result of partisan disagreements primarily over federal spending levels, health insurance subsidies under the Affordable Care Act, and other budgetary issues. Approximately 900,000 federal employees were furloughed, with another 700,000 working without pay. Essential services like Medicare, Medicaid, TSA, and Amtrak continued, but many government agencies faced partial or full suspensions of operations. This is the 21st federal government shutdown in modern U.S. history and the third under President Donald Trump's administration, marking the first shutdown since the 2018–2019 one.
