Entering the final stretch of an arduous process, the Republican-controlled Senate began voting Monday on amendments to President Donald Trump's massive tax cut and spending bill, with the goal of passing it later in the day.

U.S. Senate Republicans were trying to pass President Donald Trump's sweeping tax-cut and spending bill on Monday, despite divisions within the party about its expected $3.3 trillion hit to the nation's debt pile.

Senate Republicans can afford to lose no more than three of their own votes on the bill, but two already are opposed and others remained undecided.
