The Senate will return at 2 p.m. Monday, the last day of the fiscal year.
The House of Representatives is scheduled to meet Saturday, but the action will first come when Republicans meet privately starting at noon.
They have the potential for drama, since the Senate Friday approved a stopgap budget plan that includes Obamacare funding. House Republicans are balking at the Obamacare money.
But the Republicans differ on tactics. Some want to try again to push stripping the money, some don't. If the House does pass legislation that needs Senate approval, though, it'll have to wait till Monday to see if the Senate goes along--and the Senate's Democratic leaders have said they will not accept any dilution of Obamacare.
