The Senate will likely adjourn for two weeks after passing an adjournment resolution on Thursday.

The Hill reports that the 51-42 vote came only minutes after senators were unable to reach a consensus on a defense authorization bill. The “must pass” bill will now be dependent on one week in December when both the House and Senate will be in session. That will be the only time before the end of the year that lawmakers will have to work out the details of the controversial National Defense Authorization Act (NDAA).

The bill would provide more than $625 billion in defense spending for the Pentagon. But if the resolution to adjourn is passed by the House on Friday, legislators won’t return to the Senate to begin working out the details of the act until Dec. 9.
