Three converging events in the 1970s – the Watergate scandal, the chaotic U.S. withdrawal from the Vietnam War and revelations that FBI Director J. Edgar Hoover had abused his power to persecute people and organizations he viewed as political enemies – destroyed what formerly had been near-automatic trust in the presidency and the FBI.
In response, Congress enacted reforms designed to ensure that legal actions by the Department of Justice and the FBI, the department’s main investigative arm, would be insulated from politics. These included stronger congressional oversight, a 10-year term limit for FBI directors and investigative guidelines issued by the attorney general.
