Congressional leaders have reached an agreement altering rules for the Senate filibuster, but leaving its core intact. A deal between Senate Majority Leader Harry Reid and House Republicans would impose new caps on how often lawmakers can filibuster bills they oppose, but preserve the current 60-vote threshold needed to pass a bill through the Senate. In a statement, the public advocacy group Common Cause denounced the agreement as a “capitulation” and vowed to continue challenging the filibuster in court, saying: “It’s now clear that the Senate will not fix the filibuster and the President lacks authority to [do so]. We must turn to the judicial branch to enforce the Constitution.”
