The Senate on Monday morning began a "vote-a-rama" on proposed amendments to President Donald Trump's megabill for his second term priorities. It comes after a rare weekend session for senators, which included a dramatic 51-49 procedural vote on Saturday night to advance the massive tax and immigration bill and a forced reading of the 940-page bill by Democrats.

Senate Republicans released the latest version of President Trump's massive spending and tax bill late Friday as the GOP eyes an ambitious July 4 deadline to approve the centerpiece legislation of the president's second-term agenda.

The Senate's marathon "vote-a-rama" is underway over President Trump's "big, beautiful bill" as Republican lawmakers face a looming July 4th deadline. NBC News' Julie Tsirkin reports more from Capitol Hill and NBC News' Gabe Gutierrez reports from the White House.
