Did you guess it? The word is Bill.

Any Senator can turn an idea into a bill by introducing it in the Senate. As many as 20,000 bills may be introduced in a two-year Congress. Members of the House of Representatives introduce bills by dropping them in a box.

* Do you know how a Senator introduces a bill?
After a bill is introduced, it goes to the committee (or committees) that relate to the bill's subject matter. When a bill is passed by both houses of Congress, it is sent to the President.
