Senate Majority Leader Chuck Schumer and Minority Leader Mitch McConnell on Wednesday reached a power-sharing agreement for the evenly split Senate.

The deal was approved unanimously by the Senate on Wednesday afternoon, officially transferring control of committees to Democrats.

“We will pass the resolution through the Senate today, which means that committees can promptly set up and get to work with Democrats holding the gavels,” Schumer (D-NY) said on the Senate floor.

The agreement gives half of committee seats to Democrats and half to Republicans under a 2001 precedent. Legislation will be considered passed to the Senate floor if there are tie votes.

Democrats and Republicans each hold 50 Senate seats, but Vice President Kamala Harris is available to break ties on the Senate floor in favor of Democrats.

Schumer on Tuesday announced that socialist Sen. Bernie Sanders (I-Vt.) would be chairman of the budget committee and the more conservative Sen. Joe Manchin (D-W.Va.) would be chairman of the energy committee.

One stumbling block in the power-sharing talks was the future of the filibuster, which requires a 60-vote super majority for most legislation.

McConnell (R-Ky.) on Jan. 26 said he no longer needed written protections for the filibuster after Manchin and Sen. Kyrsten Sinema (D-Ariz.) said they opposed changing Senate rules.
