The motion to proceed on the $739 billion climate, tax and health care bill passed in a 51 to 50 vote. Vice President Kamala Harris cast the tie-breaking vote.

Now, Republicans and Democrats have up to 10 hours each to debate the spending bill, though it's not yet clear how much of the allotted debate time each side will use. After that, they'll move ahead to the consideration of amendments in a marathon session dubbed the "vote-a-rama."

Senators can offer an unlimited amount of amendments, and Republicans have already pledged to bring up several on issues like immigration, the border, energy and crime.

"What will vote-a-rama be like? It'll be like hell," Sen. Lindsey Graham, R-S.C., told reporters on Friday.
