“Thirty-one days into the new Congress and weeks after the Georgia Senate runoffs gave them 50 seats, Democrats now officially control the functioning of the Senate.
It took weeks of negotiation between party leaders to decide how Democrats and Republicans would share power and resources in the evenly divided Senate, as Senate Minority Leader Mitch McConnell stonewalled the process, trying to extract promises from Democrats about retaining the filibuster. That obstruction left Republicans chairing committees, despite the seating of a 50-50 Senate, in which Democrats, through Vice President Kamala Harris, hold the tie-breaking vote. But on Wednesday, the Senate finally passed an organizing resolution largely sharing power. The resolution was adopted by unanimous consent.”

“The belated passage of the organizing resolution eliminates the trouble Democrats ran into trying to confirm President Joe Biden’s Cabinet nominees without technically being seated as the majority. In the Senate Judiciary Committee, for example, incoming Chair Sen. Dick Durbin (D-IL) had to request that Sen. Lindsey Graham (R-SC) schedule a hearing for Biden’s attorney general nominee, because Graham still held the gavel. Graham rejected the request, underscoring the stakes of the hold-up over the organizing resolution.”
