Senate aims to hold initial vote today on Trump's "big, beautiful bill"

Washington — The Senate plans to hold a key test vote on President Trump's "big, beautiful bill" later Saturday, even as it's unclear whether the tax and spending measure has enough support to lift it over the hurdle. 

Senate Majority Leader John Thune, a South Dakota Republican, said Friday he wasn't certain he had the votes to advance the bill, as the upper chamber awaited decisions on whether a number of provisions complied with the Senate's reconciliation rules, which allow Republicans to pass the bill with a simple majority. Major policy disputes also remained.

Senate Republicans did not release the final version of their bill until late Friday night, giving senators little time to digest it before taking an initial procedural vote that's necessary to move toward final passage.
