Senators voted on a specific change, called an amendment (S.Amdt. 2887), to a pending version of the bill H.R. 4. This particular proposal was an "amendment to an amendment," which is a secondary change proposed to modify a change that was already under consideration by the Senate. In the Senate, amendments are used to update or modify the text of a bill before it is finalized. This vote required a simple majority to pass. Because it was an amendment, voting "yes" meant supporting the specific modification, while voting "no" meant keeping the bill in its previous form without that change. The amendment failed because it did not receive enough support, with both major parties split on the issue. This outcome means the bill moves forward without this specific change included. Senator Elissa Slotkin was the only member who did not cast a vote.
