The Senate is moving forward with the massive reconciliation bill after ekeing out a late-night win on Saturday to set up a fierce debate over Medicaid and other health provisions in the tax and spending cut package.
The big picture: GOP leaders want to get the bill to Trump's desk by a July 4 deadline. But it's continuing to expose divisions between moderates and conservative hard-liners and could still undergo significant changes.
Amid the drama, Sen. Thom Tillis (R-N.C.) said Sunday he wouldn't seek re-election next year after voting against starting debate on the bill and telling lawmakers he'd oppose the final version over its cuts to Medicaid.
Trump, in response, said he'd meet with Tillis' prospective GOP challengers and accused the North Carolinian of grandstanding.
By the numbers: The bill would result in 11.8 million more uninsured people by 2034, congressional scorekeepers said in a new analysis released over the weekend.
That highlighted the stakes if Republican Medicaid cuts and other health policies take effect, and is nearly 1 million higher than the 10.9 million more uninsured that CBO estimated for the House bill.
Past estimates have found that proposed Medicaid work requirements are a source of much of the coverage losses.
The Senate parliamentarian on Sunday ruled that modified Medicaid provider tax cuts and provisions that would limit Medicare coverage and Affordable Care Act premium tax credits for non-citizens can stay in the bill.
