美国，突发警告！特朗普宣布：取消！

Group 1 - President Trump unilaterally canceled $4.9 billion in foreign aid approved by Congress, facing opposition from Democrats and some Republicans, which escalates the conflict over spending control [2][3] - The $4.9 billion was designated for foreign aid, UN peacekeeping operations, and overseas democracy promotion, including $3.2 billion from the U.S. Agency for International Development, which has officially closed [2][3] - Trump's action is based on a rarely used method called "pocket veto," allowing him to stop the use of approved funds as the fiscal year ends, potentially bypassing Congress's control over key expenditures [3] Group 2 - A federal appeals court ruled that Trump did not have the authority to impose tariffs on multiple countries, although tariffs on steel, aluminum, and automobiles remain unaffected [4][5] - Trump plans to appeal the ruling to the Supreme Court, asserting that tariffs are essential for supporting American workers and manufacturing [4][5] - The court's decision poses a significant setback for Trump, creating uncertainty in trade policy that could impact financial markets and raise concerns about inflation and economic growth [5][6] Group 3 - On the same day, a federal judge temporarily blocked Trump's administration from rapidly deporting undocumented immigrants without a court hearing, citing the need for due process [6] - The ruling highlights ongoing legal challenges to Trump's strict immigration policies, which have faced numerous lawsuits since he took office [6]
