U.S. Senate Majority Leader Chuck Schumer (D-N.Y.) has opened up this week's Senate orientation to all new senators, his office said on Nov. 12.
A spokesperson told news outlets that invitations were sent to senator-elects Dave McCormick (R-Pa.) and Ruben Gallego (D-Ariz.).
"As is custom, we will invite the winner once the votes are counted," Schumer's spokesperson said previously.
Casey and Lake have not conceded yet, and officials in Pennsylvania and Arizona are still counting votes.
"I learned so much & made lasting relationships that week. Dave McCormick & Ruben Gallego will be senators for PA & AZ. They should be invited to orientation & start learning the job," Sinema wrote.
Schumer will be the top senator until January 2025, when Republicans take control of the upper chamber. He could remain as the top Democrat, but would be minority leader instead of majority leader.
Republicans have not yet chosen their top senator for the upcoming Congress. Sen. Mitch McConnell (R-Ky.) has been the top Republican for years, but is vacating the position.
Republicans, if the projected results hold, will have 53 seats in the Senate come January.
McCormick and Gallego are slated to be joined as new senators by senator-elects Angela Alsobrooks (D-Md.), Jim Banks (R-Ind.), John Curtis (R-Utah), Jim Justice (R-W.Va.), Andy Kim (D-N.J.), Bernie Moreno (R-Ohio), Lisa Blunt Rochester (D-Del.), Adam Schiff (D-Calif.), Tim Sheehy (R-Mont.), and Elissa Slotkin (D-Mich.).
Sens. Tammy Baldwin (D-Wis.), John Barrasso (R-Wyo.), Marsha Blackburn (R-Tenn.), Maria Cantwell (D-Wash.), Kevin Cramer (R-N.D.), Ted Cruz (R-Texas), Deb Fischer (R-Neb.), Kirsten Gillibrand (D-N.Y.), Josh Hawley (R-Mo.), Martin Heinrich (D-N.M.), Mazie Hirono (D-Hawaii), Tim Kaine (D-Va.), Angus King (I-Maine), Amy Klobuchar (D-Minn.), Chris Murphy (D-Conn.), Jacky Rosen (D-Nev.), Bernie Sanders (I-Vt.), Rick Scott (R-Fla.), Elizabeth Warren (D-Mass.), Sheldon Whitehouse (D-R.I.), and Roger Wicker (R-Miss.) won reelection.
