Briefly describe some of the functions of the Department of Homeland Security?u.s history paperwork

When most people think of Homeland Security, they think of
the people trying to stop terrorists from getting on airplanes.  Homeland Security does
do that, but they are also involved in a lot of other
functions.

For example, Homeland Security is the parent
agency of FEMA, the emergency management people who were in charge of the response to
Hurricane Katrina.

In addition, Homeland Security is in
charge of the ICE -- the immigration people who are supposed to be in charge of
enforcing immigration law.

Homeland Security is even
responsible for the agents who check agricultural products coming into the
country.
