A Republican senator touts tax benefits of President Donald Trump’s "big, beautiful bill" while one Democrat warns millions could lose healthcare coverage.

Fresh off announcing he'll retire next year, Sen. Thom Tillis gave a lengthy floor speech Sunday night attacking cuts to Medicaid in the "big, beautiful bill." Why it matters: The North Carolina Republican is accusing the GOP of breaking President Trump's campaign promises to protect Medicaid.

Many Republican senators dismissed the idea of overruling the Senate parliamentarian after she rejected key Medicaid provisions in Trump's tax and immigration bill Thursday, which dealt a blow to Republicans' plan to slash costs in the budget package.
