What's blocking the Senate

• Adjournment. The Senate adjourned for the midterm campaign on the night of Wednesday, September 30, 2026, and is scheduled to return the week of November 9, after the November 3 election.
• Failed cloture. The 50–46 vote on July 14, 2026 fell short of the 60 votes needed to proceed; a motion to reconsider was entered, and there has been no further Senate floor action.
• Lame-duck punt. Leaders deferred the NDAA to the post-election session rather than taking up S. 4784 before the midterms.

What happens next

The Senate is scheduled to be in session only 8 days in November and 14 days in December, counting Fridays, which aren't typically Senate workdays. Government funding expires December 11, competing for lame-duck floor time. Thanksgiving recess is November 23–27 and the Senate is out December 21–31. Sen. Mike Rounds said, "I think the NDAA will come together after the election." The expected path is a compromise text negotiated by the four Armed Services committee leaders, which wouldn't require the Senate to pass S. 4784 on the floor.
