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.

The Senate is trying to sprint ahead Monday on President Donald Trump's big bill of tax breaks and spending cuts despite a series of challenges.
