In the U.S. Congress, the parliamentarians of the House and Senate serve as formal, nonpartisan advisers to the Speaker of the House and presiding officer of the Senate respectively.
As part of its legislative duties, the Senate introduces bills and resolutions, or it considers legislation proposed by the House. A Senate committee usually examines and discusses a bill and then accepts or rejects it. The full Senate votes on accepted bills. If the bill is approved by the full Senate and originated in the Senate, the bill is sent to the House for consideration. If the approved bill originated in the House, the bill is sent to the president for his signature or veto.Other Senate duties are related to its obligation to check and balance other parts of the federal government.
