After an all-night session mostly consumed with voting down Democratic amendments, the U.S. Senate passed Donald Trump’s budget reconciliation megabill by the smallest possible margin: 51-50, with Vice President J.

It’s a pivotal moment for the Republicans, who have control of Congress and are racing to wrap up work with just days to go before the president's holiday deadline Friday.

All told, the Senate bill includes $4.5 trillion in tax cuts, according to the latest CBO analysis, making permanent Trump’s 2017 rates, which would expire at the end of the year if Congress fails to act, while adding the new ones he campaigned on, including no taxes on tips.
