President pro tempore. A president pro tempore or speaker pro tempore is a constitutionally recognized officer of a legislative body who presides over the chamber in the absence of the normal presiding officer. The phrase pro tempore is Latin for the time being. In Argentina, a similar role is carried by the Provisional President of the Argentine Senate in the absence of the Vice President of Argentina who is designated, by the 1994 amendment to the 1853 Constitution, as the Senate President.
In the United States Senate, the majority leader is the chief spokesperson for the majority party, as the president of the Senate is also the Vice-President of the United States, and the President pro tempore, though technically a substitute for the president of the Senate, is in reality a largely ceremonial position (albeit powerful nonetheless, being third in line of succession to the presidency).
