The Transportation Security Administration (TSA) was created in response to the terrorist attacks of September 11, 2001 as part of the Aviation and Transportation Security Act signed into law by President George W. Bush on November 19, 2001. TSA was originally in the Department of Transportation but was moved to the Department of Homeland Security in March 2003.
TSA’s mission is to protect the nation’s transportation systems by ensuring the freedom of movement for people and commerce. In February 2002, TSA assumed responsibility for security at the nation’s airports and by the end of the year had deployed a federal work force to meet challenging Congressional deadlines for screening all passengers and baggage.
