Senate Majority Leader Chuck Schumer and Minority Leader Mitch McConnell are still at odds about how to work in a split chamber.
The Senate now has a 50-50 split, but with Vice President Kamala Harris breaking ties, Democrats have control.
But here's where things get tricky — Harris won't be there every day.
So Schumer and McConnell still need to figure out a plan to decide which legislation reaches the floor.
McConnell wants Schumer to protect a rule that requires 60 votes to advance legislation, but Schumer hasn't committed to that.
That leaves leaving the door open for Democrats to pass some parts of their agenda by a simple majority.
