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.

U.S. Senate Republicans passed President Donald Trump's massive tax-and-spending bill on Tuesday by the narrowest of margins, advancing a package that would slash taxes, reduce social safety net programs and boost military and immigration enforcement spending while adding $3.

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.
