President Donald Trump’s decision to freeze billions in infrastructure funds for Democratic-led states has heightened tensions in Washington as the U.S. government shutdown entered its fourth day, making it one of the longest in recent history. The White House withheld $28 billion earmarked for New York, California, and Illinois, fueling concerns that the move targets political rivals while negotiations to reopen the government stall. While some Republicans share Tillis’ concerns, others back Trump’s hardline approach. Democrats, meanwhile, remain firm in their demands, including a permanent extension of Affordable Care Act subsidies and protections against the White House withholding funds already allocated by Congress. The longer the shutdown drags on, the more likely Republicans may share in the political fallout heading into the midterm elections.
