WATCH: Senate reads full text of President Trump's 'Big, Beautiful Bill'

Senate Republicans voting in a dramatic late Saturday session narrowly cleared a key procedural step as they race to advance President Donald Trump’s package of tax breaks, spending cuts and bolstered deportation funds by his July Fourth deadline.

The tally, 51-49, came after a tumultuous session with Vice President JD Vance on hand if needed to break the tie.

The 940-page bill was released shortly before midnight Friday, and senators are expected to grind through the hours of all-night debate and amendments in the days ahead. If the Senate is able to pass it, the bill would go back to the House for a final round of votes before it could reach the White House.

President Donald Trump posted on Truth Social Saturday evening: "Tonight we saw a GREAT VICTORY in the Senate with the “GREAT, BIG, BEAUTIFUL BILL,” but, it wouldn’t have happened without the Fantastic Work of Senator Rick Scott, Senator Mike Lee, Senator Ron Johnson, and Senator Cynthia Lummis. They, along with all of the other Republican Patriots who voted for the Bill, are people who truly love our Country! As President of the USA, I am proud of them all, and look forward to working with them to GROW OUR ECONOMY, REDUCE WASTEFUL SPENDING, SECURE OUR BORDER, FIGHT FOR OUR MILITARY/VETS, ENSURE THAT OUR MEDICAID SYSTEM HELPS THOSE WHO TRULY NEED IT, PROTECT OUR SECOND AMENDMENT, AND SO MUCH MORE. GOD BLESS AMERICA &, MAKE AMERICA GREAT AGAIN!!!"
