Operation Gatekeeper was a measure implemented during the presidency of Bill Clinton by the United States Border Patrol (then a part of the Immigration and Naturalization Service (INS)), aimed at halting illegal immigration to the United States at the United States–Mexico border near San Diego, California. According to the INS, the goal of Gatekeeper was "to restore integrity and safety to the nation's busiest border." Operation Gatekeeper was announced in Los Angeles on September 17, 1994, by U.S. Attorney General Janet Reno, and was launched two weeks later on October 1.
