A marathon voting session on President Donald Trump’s sweeping domestic policy bill is underway in the Senate and has stretched overnight into Tuesday after a weekend of negotiations and delays.

The Senate narrowly approved President Donald Trump's signature second-term policy bill, a nearly 900-page package packed with tax cuts and other campaign promises, in a major legislative victory for the president that came after a tense debate within his party that stretched on for nearly four days.

The Alaska Senator called her decision on the bill “probably the most difficult and agonizing 24-hour legislative period that I’ve encountered."
