近7年来首次 美国联邦政府正式“关门”

Group 1 - The U.S. federal government has shut down for the first time in nearly seven years due to the Senate's failure to pass funding bills, affecting hundreds of thousands of federal employees who face forced leave or layoffs [3][4]. - The shutdown has led to the implementation of "orderly shutdown" plans by various government agencies, with certain departments like the military and law enforcement remaining operational [3][4]. - The shutdown is a result of ongoing partisan conflicts in Congress, with temporary funding measures often being used to keep the government running amid budget disagreements [4][5]. Group 2 - Approximately 800,000 federal employees will be placed on unpaid leave, and contractors will face delays in payment due to the shutdown [6]. - Low-income families will experience immediate impacts, particularly in areas such as transportation, travel, healthcare, and public health, with broader economic costs also being significant [7]. - Historical context shows that the U.S. government has experienced over 20 shutdowns since the 1970s, with the last major shutdown occurring during the Trump administration, lasting 35 days and resulting in over $10 billion in economic losses [8].
