Federal funding expired at midnight after Trump and lawmakers failed to agree on a deal to keep the lights on, prompting agencies to wind down services, while the White House warned of "imminent" firings of public sector workers. Senate Democrats - who are demanding extended health care subsidies for low-income families - refused to help the majority Republicans approve a House-passed bill that would have reopened the government for several weeks while negotiations continue. Voting in the Senate is now adjourned until Friday, meaning hopes for a quick resolution have been frustrated. "They said to us, 'we will open the government, but only if you give billions of dollars of funding for health care for illegal aliens.' But it bars undocumented immigrants from receiving the health care benefits Democrats are demanding, and the party has not called for a new act of Congress to change that.
