Final answer:
The FBI, or Federal Bureau of Investigation, operates domestically within U.S. borders under the Department of Justice. It enforces federal laws and investigates crimes. The FBI Director is appointed by the President and confirmed by the Senate.
Step-by-step explanation:
The FBI, which stands for the Federal Bureau of Investigation, is the chief federal law enforcement agency within the United States and falls under the Department of Justice. It operates domestically and has a broad range of responsibilities including enforcing federal laws and investigating a variety of federal crimes. The FBI was established in 1919 within the Department of Justice and has since been involved in overseeing and implementing law enforcement and intelligence activities within the country. This contrasts with agencies like the CIA, which operates overseas. J. Edgar Hoover, known for significantly expanding the FBI's role during his tenure, was appointed to oversee the Bureau's new division in 1919, which later became the FBI as we know it today.
Under the oversight of the President and Congress, the Department of Justice captures a vast network of offices and agencies, with the FBI being one of these. The Director of the FBI is appointed by the President and must be confirmed by the Senate. This ensures that the federal law enforcement is accountable to elected officials and ultimately, to the public. The diverse roles within the Department of Justice, including those at the FBI, emphasize the coordinated effort to uphold law and order while protecting the civil liberties of American citizens.
