Republican House Speaker Mike Johnson predicts the federal government shutdown may become the longest in history, refusing to negotiate with Democrats until they pause healthcare demands. The shutdown has halted government operations and caused disruptions, with no end in sight. The debate centers around the Affordable Care Act subsidies expiring for millions of Americans. Johnson insists Republicans are willing to discuss healthcare but demand the government be reopened first. The situation is complicated by the Trump administration's actions regarding federal workers and funding.
