Sen. Ron Johnson of Wisconsin wants Tuesday's GOP leadership vote delayed so the conference can first review its midterm losses. Four other senators, including Rick Scott and Mike Lee, joined his request.
Senators David McCormick and Jim Banks did not sign but also want a pause. Thune, the current majority leader, is expected to seek another term, and no one has declared against him.
Unless the conference agrees to the delay, the vote happens Tuesday morning. Democrats won 54 Senate seats, and that could rise depending on races in Mississippi and Alaska.
