What is the chief of the US?

Answer 1

; "Chief Legislator The President of the United States is also the chief legislator. He can recall Congress into a special session. He may veto the bills passed by Congress, and use his influence on his colleagues in Congress to get a bill passed or proposed. Again, all of his actions are limited by other branches of government: Congressmen do not have to pass any laws during the special session, Congress can override the president's veto by a two-thirds majority, and no one in Congress must succumb to the president's pressure." - http://library.thinkquest.org/11492/convention/powers.html
