Describe in detail the steps of a bill becoming a law.

In the United States, according to the Constitution, there
are several steps in a bill becoming a law.  These are extensions to the principles and
ideas that are found within the Constitution.  A bill starts out as an idea that is
motivated from particular constituents of a member of Congress.  There is some need that
needs to be addressed and this need is what forms legislation.  A bill can start in
either the House of Representatives or the Senate, although the Constitution states that
all revenue bills must start in the House.  The bill is refined and developed in
committee action, where a select group of expert Congressional members debate and
discuss different aspects of the topic area and form the actual language of the bill.
Once submitted and passed through committee, the bill goes to the floor of the
particular chamber of Congress (House or Senate) for floor action, where members have
their particular say on the bill in terms of discussion and discourse.  Once a form of
the bill has been agreed upon, the chamber votes.  If there is a majority, then it goes
on to the next portion of Congress for further debate and refining.  If the bill is
voted in approval, it goes to the President's desk, who can choose to sign the bill or
send it back to Congress for further changes.  Once signed, the bill becomes a law.  If
the Congress can muster up a 2/3 vote in each portion to override the Presidential veto,
the bill can become law in this manner, as well.
