Officers and Staff of the Senate
Floor Leader Responsibilities
The "offices" of the majority and the minority leader, as we know them today, are of recent development in the history of the Senate although individual Senators since 1789 have assumed leading roles in the determination of what the Senate would or would not do. Some of these Senators, at one time or another, have stood high in the ranks of their respective political parties. The power or influence of some Senators, in various periods of our history, to guide or lead their respective parties, or even the Senate itself, in the determination of a legislative program, has been particularly noteworthy. Caucuses of Senators of a particular party, of a common interest, of a geographical area, or of some "blocs" have been called from time to time from the beginning of the first Senate for all kind of purposes, including the determination of the position to be taken on certain proposed legislation, or such things as to determine the names and sizes of the committees. These meetings, however, were not invoked to perform as organized political caucuses for the purpose of selecting persons to serve as floor leaders for the parties during the sessions of the Senate until the latter part of the 19th century.
