Members of the Senate have several options to block legislation. Here are a few examples:
Filibuster: A senator may hold the floor for an extended period to delay or prevent a vote on a bill. A filibuster can be ended by a vote of 60 senators to invoke cloture.
Holds: A senator may place a "hold" on a bill or nomination, which signals an intention to object to the bill or nomination and can delay the legislation from moving forward.
Amendments: Senators may offer amendments to bills that could substantially change the content of the legislation, which may cause the bill's supporters to withdraw their support or the bill to be rejected.
Committee Actions: Senators can vote against a bill in committee or block a bill from being reported out of committee, which can effectively prevent the bill from being considered by the full Senate.
It's important to note that the Senate's rules and procedures provide members with various tools to delay or block legislation, but ultimately, a bill can still pass with a simple majority vote if the supporters of the bill can gather enough votes to overcome any objections or obstacles.
