The official seal and motto of the Federal Bureau of Investigation

The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States and its principal federal law enforcement agency. Operating under the jurisdiction of the United States Department of Justice, the FBI is also a member of the U.S. Intelligence Community and reports to both the Attorney General and the Director of National Intelligence.


20th century[]

Established in 1908 as the "Bureau of Investigation", the FBI headquarters is the J. Edgar Hoover FBI Building, located in Washington, D.C.. (TXF: "Pilot", et al.) Entry into the FBI requires the potential Agent to pass a psych screening. (TXF: "Pusher") However, some individuals are eligible for entitlement of honorary agent. (TXF: "The Goldberg Variation")

In 1946, Director J. Edgar Hoover opened the FBI's X-Files unit, a department that focused on unsolved cases that seem to have an unexplained, paranormal element. (TXF: "Shapes", "Pilot") The cases in this department were labeled as X-Files by the FBI and were stored in the basement of the J. Edgar Hoover FBI Building. From 1992, Special Agents Fox Mulder and Dana Scully were assigned to work on the X-Files, although the department was shut down on several occasions.

21st century[]

Special Agents John Doggett and Monica Reyes were assigned to the X-Files in 2002. (TXF: "The Truth")

During the early 2000s, the FBI's director was Robert Mueller. In early 2018, the FBI did not have a very good relationship with U.S. President Donald Trump, as he disliked it. (TXF: "This")
