The Senate voted 50-50 on Trump's megabill. Vice President JD Vance cast the tie-breaking vote to pass the massive tax and immigration bill. A final vote on Trump's megabill is now underway in the Senate. It needs 51 votes to pass. Some Republican senators to watch are Susan Collins, Lisa Murkowski, Ron Johnson and Rand Paul.

Republican leaders worked through the night to win over holdouts as they raced to pass President Trump’s tax and spending package by their self-imposed July 4 deadline.

The measure would extend trillions of dollars in tax cuts from Trump’s first term and implement new campaign promises while spending billions on immigration enforcement.
