How many times may a senate speak on a Bill?

In the U.S. Senate, there is no formal limit on the number of times a senator can speak on a bill during debate. Each senator can participate in discussions as long as they adhere to the rules of the Senate and the specific context of the debate, such as time limits set by unanimous consent or by the Senate majority. However, individual senators may be limited in speaking time by the Senate leadership or through agreements made before the debate.
