Proposing an amendment to the Constitution of the United States to provide that debate upon legislation pending before the Senate may not be brought to a close without the concurrence of a minimum of three-fifths of the Senators.

HJRES 4 proposes a constitutional amendment to require a three-fifths vote (60 Senators) to end debate on most Senate legislation, instead of the current simple majority for cloture. This would directly affect Senate procedure by making it harder to advance bills without broad consensus, applying to all pending legislation except presidential nominations. The key provision changes the threshold for ending debate from a simple majority to 60 votes, as specified in the proposed constitutional text. If passed, this would alter how the Senate manages floor time for bills, though it would require ratification by 38 states to become law.
