The Senate lacks the votes to pass a House GOP spending bill.

Forty-two Democrats have come out in opposition to the measure, which is also facing opposition in the House.

Two Republicans also say they will vote against the bill, leaving it short of the 60 votes necessary to pass it if it can get through the lower chamber.

While it is possible that members could shift their positions, it definitely means the federal government is closer to a shutdown than it has been since a 16-day closure in 2013.

The government would shut down on Saturday without action by Congress.
