由于一项最后一刻达成的拨款协议未能获得众议院通过，美国政府于2026年1月31日部分停摆。参议院批准了一项拨款法案，以维持大多数机构运转至9月，但国土安全部仅获得两周的拨款。此次停摆发生在2025年43天的拨款中断之后，并且正值边境巡逻队特工枪杀亚历克斯·普雷蒂后，围绕移民执法问题的政治紧张局势加剧之际。预计众议院将于周一复会，这将有助于谈判，但围绕警务策略和监督的紧张局势依然高涨。 The US government partially shut down on 31 January 2026 after a last-minute funding deal failed to pass the House of Representatives. The Senate approved a funding bill to keep most agencies running until September but only funded the Department of Homeland Security for two weeks. The shutdown follows a 43-day funding lapse in 2025 and comes amid political tensions over immigration enforcement after the fatal shooting of Alex Pretti by a Border Patrol agent. A House return on Monday is expected to facilitate negotiations, though tensions over policing tactics and oversight remain high.
