Answer:
filibustering
Step-by-step explanation:
A senator who agrees to vote for a tax cut bill that he or she disagrees with in order to receive another senator’s vote on a climate change bill that he or she has proposed is engaged in filibustering. Filibustering involves a senator trying to prevent a bill to be voted on in the senate floor unless the senator who proposed the bill is willing to vote favourable for his own bill. Filibustering is simply the process of blocking bills to be voted on in the senate floor. This is a tactic used by senators to pressure fellow senators to support their own bill in exchange for a cloture of the filibustering.
