The position of Senate majority leader is not in the Constitution. The best idea I've heard floated is to turn to the Constitution for Senate leadership.
With Republicans taking control of the Senate for the first time in four years, the party will need to select a new Senate Majority Leader from its ranks, and an unlikely candidate has emerged: Vice President-elect JD Vance.
The idea was floated by top conservative commentator and staunch supporter of President-elect Donald Trump, Charlie Kirk, founder of Turning Point USA. Kirk pitched the proposal on the podcast of fellow conservative Glenn Beck, saying that the idea came from Republican Sen. Mike Lee of Utah during "a 1 a.m. phone call."
While the vice president is an important figure in the Senate's administrative processes, giving control of the legislative agenda and committee appointments to a member of the executive branch is a move with no recent constitutional precedent.
Kirk said that the basis of the appointment would be John Adams' leadership of the Senate while he was George Washington's vice president, though the role of majority leader did not exist at the time.
The vice president presides over the Senate, overseeing bureaucratic processes like the swearing-in of new members. They also have a tie-breaking vote for legislation, which Vice President Kamala Harris used frequently when the chamber was split 50-50.
However, Kirk argued that the Senate rules allowed a vice president to take more active control over proceedings, telling Beck, "John Adams presided over the U.S Senate as Senate Majority Leader 200 years ago, as vice president of the United States. I think JD Vance should be president of the Senate and become Senate Majority Leader.
"The Constitution says that the vice president is the highest ranking officer in the Senate, and when he sits in the chair, that's the way it is."
