President pro tem of the Senate


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.
