VERIFY: While there's precedent for determining a majority leader in a 50-50 Senate, there aren't official rules Last time the Senate was split, the party of the Vice President was awarded the majority leader under a powersharing agreement. Author: VERIFY, Terry Spry Jr. Published: 8:24 PM EST January 6, 2021 Updated: 8:24 PM EST January 6, 2021 Currently, both Raphael Warnock and Jon Ossoff, both Democrats, lead in the two Senate runoffs held in Georgia earlier this week. If the results hold without massive shifts from recounts, both will win and put the Senate at 50-50. In that case, the Vice President will get the tiebreaking vote.
