Read the article below and use the information you find there to answer the questions that
follow.
A bill is sent to the President of the United States when it has passed both houses of
congress. A majority vote in both the House of Representatives (435 members) and the
Senate (100 members) is needed for the bill to be passed on to the President. The
majority vote is a majority of the members present, as long as more than one-half of all
the members are present. More than one-half of the members make up what is called a
quorum. Once the bill comes to him, the President may either sign the bill, making it a
law, or he can veto the bill. His veto sends the bill back to Congress. Congress can still

make the bill a law by overriding the Presidential veto. To over ride the veto,
of the

members of each legislative body must vote to override it. Again, this is
