Senators will now begin a period of debate, lasting up to 20 hours, on various amendments to the House version of the bill, which passed in May. After debate, they will begin a “vote-a-rama” — a period of successive votes on the offered amendments. Mitch McConnell, the majority leader, could introduce a substitute amendment that would replace all of the others.

Finally, the legislation would move to a final vote. If it passes, the same version will have to be approved by the House before being sent to the president to sign.
