The Senate has begun a marathon voting session, known as a "vote-a-rama," on President Donald Trump's "big, beautiful bill," which includes significant tax cuts and spending changes. This session allows senators to propose unlimited amendments, leading to a series of rapid-fire votes. The bill, which aims to make Trump's 2017 tax cuts permanent, has sparked intense debate over its potential impact on the federal deficit and Medicaid.

President Trump is pushing for the bill to be passed by July 4, but the Senate must first navigate this complex amendment process. Senate Majority Leader John Thune expressed optimism about securing enough votes, despite opposition from some Republicans. Senators Thom Tillis and Rand Paul have already voted against advancing the bill, citing concerns over Medicaid cuts that could leave nearly 12 million more people uninsured by 2034.

The Congressional Budget Office (CBO) estimates that the Senate's version of the bill would cut federal support for Medicaid by $930 billion over a decade. The bill also proposes work requirements for certain Medicaid recipients, which has been a point of contention. Senate Minority Leader Chuck Schumer criticized the bill for its potential to add trillions to the national debt, while Republicans argue it will spur economic growth.

The vote-a-rama began after a weekend of negotiations, with senators expected to vote on amendments throughout the day. The bill's path remains uncertain, as it must return to the House for approval of any Senate changes. Some House Republicans have expressed concerns about these revisions.

The bill's provisions, such as the permanent extension of tax cuts and changes to green energy subsidies, have been divisive. Senate Republicans are working to address holdouts, while Democrats aim to challenge the bill's controversial aspects through amendments.
