WASHINGTON (AP) — Republican and Democratic lawmakers at an impasse on reopening the federal government provided few public signs Sunday of meaningful negotiations talking place to end what has so far been a five-day shutdown. Leaders in both parties are betting that public sentiment has swung their way, putting pressure on the other side to cave. Democrats are insisting on renewing subsidies to cover health insurance costs for millions of households, while President Donald Trump wants to preserve existing spending levels and threatening to permanently fire federal workers if the government remains closed.
