This vote was on an amendment, which is a formal proposal to change the language or requirements of a bill already being considered by the Senate. In this case, the Senate was deciding whether to add specific new terms or modifications, identified as S.Amdt. 1266, to the underlying bill H.R. 1968. In the Senate, amendments are typically voted on before the final vote on the entire bill. This process allows senators to shape the legislation by adding, removing, or changing specific parts of the proposal. This particular vote required a simple majority of those present to pass. A 'yea' vote supported adding the new language, while a 'nay' vote opposed the change. The amendment was soundly defeated with a majority of both parties voting against it. Because the amendment failed, H.R. 1968 remains in its previous form, and the Senate will continue its work on the bill without these proposed changes.
