In the United States of America it has two assemblies or houses which are known as bicameral legislature of the federal government. The two assemblies are called House of Representatives and senate.

The congressional hearings are a practice adopted by the congressional committee which will collect the information analyse that before making policy decisions.

During the debate on a bill or an amendment the member of the congress will use the term "move to strike the last word" of the amendment or bill under debate. It is part of the house proceeding and it is mere formality.
