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.
This position recognises that the Senate is democratically elected and possesses constitutional powers nearly the equal of the House of Representatives. To fulfil the role the Constitution allows the Senate in relation to the government, the Senate is able to scrutinise and judge the activities, policies and legislation of the government. This is why the Senate is known as a house of review.
