A partial US government shutdown has begun, effective October 1, 2025, after Congress failed to pass the necessary funding bills by the deadline. This marks the first shutdown in nearly seven years, resulting from a stalemate over funding for the new fiscal year. The impasse arose from a disagreement between Senate Republicans and Democrats, who were at odds over the inclusion of policy attachments in the funding bill, with Democrats seeking a commitment to address expiring health care subsidies and Republicans pushing for a "clean" funding measure without any attachments.
