Senate wrangles over Trump's 'one big beautiful bill' to continue.

senators scheduled to start voting on a potentially long list of amendments to Donald Trump’s “one big beautiful bill” beginning at 9 am EDT.

Yesterday, Republicans in the Senate Republicans pushed Trump’s sweeping tax cut and spending bill forward in a marathon weekend session even as a nonpartisan forecaster said it would add an estimated $3.3tn to the nation’s debt over a decade.

The estimate by the congressional budget office of the bill’s hit to the $36.2tn federal debt is about $800bn more than the version passed last month in the House of Representatives.

“Republicans are doing something the Senate has never, never done before, deploying fake math and accounting gimmicks to hide the true cost of the bill,” Democratic Senate minority leader Chuck Schumer said as debate opened on Sunday.

The Senate only narrowly advanced the tax-cut, immigration, border and military spending bill in a procedural vote late on Saturday, voting 51-49 to open debate on the 940-page megabill.

Senator Thom Tillis of North Carolina, one of two Republicans who voted to block the bill, explained his position in a speech to the Senate, saying White House aides had failed to give Trump proper advice about the legislation’s Medicaid cuts.

“What do I tell 663,00 people in two years, three years, when president Trump breaks his promise by pushing them off of Medicaid because the funding’s not there anymore,” Tillis said, referring to his constituents.

Tillis said he would not seek re-election next year, after Trump threatened to back a primary challenger in retribution for Tillis’ Saturday night vote against the bill.

On Sunday, Trump celebrated Tillis’ announcement as “Great News!” on Truth Social and issued a warning to fellow Republicans who have concerns over the bill. “REMEMBER, you still have to get reelected. Don’t go too crazy!” Trump wrote in a post.
