A lot of [senators] feel strongly that we need to keep that 60 vote threshold, and I’m one of them.
I will support preserving the Senate filibuster and its 60-vote threshold for passing legislation.
Occurrences
Evidence
Rule XXII provides that cloture on most pending Senate business is invoked by "three-fifths of the Senators duly chosen and sworn," with a higher threshold for rules changes.
For cloture on H.R. 1968, the Senate listed "Required For Majority: 3/5" and "Vote Result: Cloture Motion Agreed to" with 62 yeas; Curtis voted yea.
For cloture on the motion to proceed to H.R. 5371, the Senate listed "Required For Majority: 3/5" and "Vote Result: Cloture on the Motion to Proceed Rejected" despite 54 yeas; Curtis voted yea.
AP reported Curtis said: "The filibuster forces us to find common ground in the Senate" and "I'm a firm no on eliminating it."
The Guardian reported that Curtis rejected Trump's suggestion and reaffirmed opposition to ending the rule requiring 60 votes to advance legislation.
AP reported that most Senate Republicans did not want to lower the 60-vote threshold and quoted Curtis on a proposed workaround: "the reason or method doesn't matter - it's breaking the filibuster."
Assessments
Curtis promised to support preserving the Senate legislative filibuster and its 60-vote threshold. During his Senate term, the 3/5 cloture threshold remained in force and was applied in legislative votes, including votes where 54 yeas failed and 62 yeas succeeded. Curtis also publicly opposed eliminating or bypassing the filibuster when pressured by President Trump, directly aligning with the promise. Because the rule remained intact and Curtis supported preserving it during the same federal Senate term, this counts as delivered.
