Who decides how long a bill will be debated in senate?

Answer 1

In the U.S. Senate, the length of debate on a bill is primarily determined by unanimous consent agreements. If no agreement is reached, the Senate operates under its rules, which allow for extended debate unless a cloture motion is invoked to limit discussion. A cloture motion requires a minimum of 60 votes to pass, effectively ending debate and moving the bill to a vote. The Majority Leader often plays a key role in negotiating the terms of the debate.
