Congress has little time to avoid a government shutdown that is set to begin at 12:01 a.m. on Oct. 1. They are nowhere near an agreement.

After a six-week summer recess, lawmakers return to the Capitol on Monday facing a changed political landscape but a vexing, very familiar problem: figuring out how to avert a shutdown.

They have just three weeks to do so. Funding for the government runs out at the end of the fiscal year on Sept. 30, and former President Donald Trump is urging Republicans to force a shutdown unless certain demands are met. A shutdown would close federal agencies and national parks, while limiting public services and furloughing millions of workers just weeks before the election.
