The government shutdown hit its 40th day on Sunday as the Senate prepared to reconvene for day two of its rare weekend session to try to move the needle as lawmakers sounded the alarm on rising disruptions to flights and beneficiary programs.

The Senate was set to meet Sunday afternoon at 1:30 p.m., with Republicans scheduled to go to conference before then to determine a way forward. Senators are working to finalize a three-bill “minibus” that would fund some of the government. Majority Leader John Thune (R-SD) has a plan to vote on the House continuing resolution as well as the appropriations bill, but it’s unclear whether it will be enough to get Democrats on board.
