How Congress Makes Laws
A new law starts out as a document
called a bill. First a member of the
House or the Senate introduces a bill.
Then it goes to a small group of
representatives or senators called a
committee. There are many
committees. Committees have the
power to make changes in bills. They
also decide which bills the whole House
or Senate will vote on.
Once the bill is ready, the House or the
Senate votes on it. If more than half of
the members who vote on a bill approve
it, the bill passes, or gets approved. It
then goes to the other house for
approval. In order to become a law, a bill
must be passed by both houses.
A bill passed by both houses goes to the
president of the United States. If the
president signs the bill, it becomes a law.
However, the president can veto, or
reject, a bill. A vetoed bill can still
become a law, however. This happens if
two thirds of both houses of Congress
vote to override, or undo, the veto.
Executive Branch
The executive branch puts into use the
laws that the legislative branch makes.
The president of the United States leads
the executive branch.
The President
Presidents serve four-year terms. Since
1951 presidents have been limited to
two terms. The vice president takes over
if the president dies, gives up the job, or
is unable to serve.
A group called the electoral college elects
the president and the vice president
every four years. Voters in a national
election tell the electoral college members
from their state how to vote.
Congress can accuse the president of
breaking the law. This is called
impeachment. The Senate decides
whether the president is guilty. A guilty
president must resign, or step down.
Congress has impeached two
presidents—Andrew Johnson and Bill
Clinton—but the Senate found them
both not guilty.
Executive Power
The president decides what the
government should do. This is called
making policy. A part of making policy
is recommending laws for Congress to
pass. Another part is dealing with
foreign countries. As commander in

chief of the armed forces, the president
can send soldiers into battle in foreign
countries. However, only Congress may
declare war.
The president also oversees the departments
and government agencies that are
part of the executive branch. These
groups carry out laws and policies of all
kinds.
After the Department of Homeland
Security was created in 2002, there were
15 departments in all. The president
appoints their leaders. The leaders form
a group that is called the Cabinet. The
Cabinet gives advice to the President.
Judicial Branch
The judicial branch, or judiciary, is a
system of courts. Officials called judges
run the courts. The courts use the U.S.
Constitution and other laws of the U.S.
government to settle cases.
The president of the United States
appoints all federal judges, but the Senate
must approve them. Once approved,
the judges serve until death or retirement.
Federal judges, like presidents,
can be impeached.
Lower Courts
The district courts are the lowest level of
U.S. courts. District court trials usually
