The Transportation Security Administration (TSA) is an agency of the U.S. Department of Homeland Security that has authority over the security of the traveling public in the United States.〔49 USC § 114(d)〕 The TSA was created as part of the Aviation and Transportation Security Act, sponsored by Don Young in the United States House of Representatives〔(【引用サイトリンク】title=THOMAS )〕 and Ernest Hollings in the Senate,〔(【引用サイトリンク】title=THOMAS )〕 passed by the 107th U.S. Congress, and signed into law by President George W. Bush on . Originally part of the United States Department of Transportation, the TSA was moved to the Department of Homeland Security on . ==History and organization== The TSA was created as a response to the September 11, 2001 attacks. Its first administrator, John Magaw, was nominated by President Bush on December 10, 2001, and confirmed by the Senate the following January. The agency's proponents, including Transportation Secretary Norman Mineta, argued that only a single federal agency would better protect air travel than the private companies who operated under contract to single airlines or groups of airlines that used a given terminal facility. The organization was charged with developing policies to protect U.S. transportation, especially in airport security and the prevention of aircraft hijacking. With state, local, and regional partners, the TSA oversees security for highways, railroads, buses, mass transit systems, pipelines and ports. However, the bulk of the TSA's efforts are in aviation security. The TSA is responsible for screening passengers and baggage at more than 450 U.S. airports.〔(TSA Jobs )〕 Private screening did not disappear under the TSA, which allows airports to opt out of federal screening and hire firms to do the job instead. Such firms must still get TSA approval under its Screening Partnership Program (SPP) and follow TSA procedures. Among the U.S. airports with privately operated checkpoints are San Francisco International Airport; Kansas City International Airport; Greater Rochester International Airport; Tupelo Regional Airport; Key West International Airport; Charles M. Schulz – Sonoma County Airport; and Jackson Hole Airport.〔(TSA Announces Private Security Screening Pilot Program ), TSA press release June 18, 2002 〕〔(TSA Awards Private Screening Contract ), TSA press release January 4, 2007〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Transportation Security Administration」の詳細全文を読む スポンサード リンク
