Once a bill passes both chambers, the only way it can become law is if it is signed by the President of the United States.

True.

The United States Government is composed of three major powers that play their own respective roles to make America a great country. The three major powers are called: Executive, Legislative, and Federal/Judicial. The Legislative Department are composed of congressmen and senators responsible in making bills that are later passed on to the Executive department. The Executive department is the Office where the President resides, it has the power to approve all the bills that the Legislative has proposed. The approval of the President will then make the bill into a law.

The Judiciary or Federal department is responsible in protecting the rights of the people of the State and in enacting the laws that have been made based on the Constitution of the United States.
