The US Senate has started debating over the highly anticipated “big, beautiful bill” in an all-night session on Sunday, with Republicans wrestling President Donald Trump’s big bill over tax breaks, increased spending on immigration enforcement, spending cuts over healthcare to mount over Democratic opposition with a July 4 deadline. The formal debate began in the Senate with Democratic lawmakers demanding the Senate clerks to read the full 940-page bill aloud, in order to highlight their arguments that the public is largely unaware of what President Trump branded “package” actually contains, and delay the final voting until Monday. Some in Congress are fighting against the One Big Beautiful Bill. The American people don’t like that. This bill delivers $10,000 more a year for working families, tax-free tips and overtime, & real border security. You were sent to do your job. Vote YES. Or get out the way. pic.twitter.com/1JbzlkkTwp — The White House (@WhiteHouse) June 29, 2025 Republicans have been working throughout the weekend, huddling with opposition voices within the party lines to strike a middle ground but the outcome still remains highly uncertain and volatile. The GOP leaders are rushing to meet Trump’s July 4 deadline to pass the bill but have been unable to garner enough support to cross the procedural hurdle in a tense scene on Saturday, which required phone calls by Trump and a visit by Vice President JD Vance to the US Capitol to keep the bill on track. Republican Senator from North Carolina, Thom Tillis, announced on Sunday that he was not seeing a reelection, a day after voting against Trump’s budget bill on taxes. Tillis had expressed his concerns over the impact Medicaid cuts would have on his constituents. After the debate over the bill gets over, amendments would be brought up for consideration in a marathon session, also known as vote-a-rama. The changes made in the bill are supposed to pile trillions of dollars of national debt in the United States. According to an analysis by the Congressional Budget Office, if Trump’s ‘big, beautiful bill’ becomes a law, about 11.8 million Americans would become uninsured by 2034. The package would also increase the deficit by nearly $3.3 trillion over the decade.
