The '''President of the Senate''' (not to be confused with the President Pro Tempore of the Senate) presides over sessions of the United States Senate, although their powers are considerably less than the Speaker of the House. The president votes only in case of a tie. The position of Senate President is granted by virtue of office to the [[Vice President]], although in practice, they rarely preside over Senate sessions, instead usually delegating to junior Senators, to allow them to learn Senate procedure. <ref>[http://www.senate.gov/reference/glossary_term/appropriation.htm] US Senate Reference</ref>
