The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States and its principal federal law enforcement agency. An agency of the United States Department of Justice, the FBI is a member of the U.S. Intelligence Community and reports to both the attorney general and the director of national intelligence. A leading American counterterrorism, counterintelligence, and criminal investigative organization, the FBI has jurisdiction over violations of more than 200 categories of federal crimes. The FBI maintains a list of its top 10 most wanted fugitives.
Although many of the FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and NCA and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection abroad, the FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in smaller cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the director of national intelligence.
Despite its domestic focus, the FBI also maintains a significant international footprint, operating 60 Legal Attache (LEGAT) offices and 15 sub-offices in U.S. embassies and consulates across the globe. These foreign offices exist primarily for the purpose of coordination with foreign security services and do not usually conduct unilateral operations in the host countries. The FBI can and does at times carry out secret activities overseas, just as the CIA has a limited domestic function. These activities generally require coordination across government agencies.
The FBI was established in 1908 as the Bureau of Investigation, the BOI or BI for short. Its name was changed to the Federal Bureau of Investigation (FBI) in 1935. The FBI headquarters is the J. Edgar Hoover Building in Washington, D.C.
Mission, priorities and budget
The mission of the FBI is to "protect the American people and uphold the Constitution of the United States".
Currently, the FBI's top priorities are:
Protect the United States from terrorist attacks
Protect the United States against foreign intelligence operations, espionage, and cyber operations
Combat significant cybercriminal activity
Combat public corruption at all levels
Combat transnational criminal enterprises
Combat major white-collar crime
Combat significant violent crime
In the fiscal year 2019, the Bureau's total budget was approximately $9.6 billion.
In the Authorization and Budget Request to Congress for fiscal year 2021, the FBI asked for $9,800,724,000. Of that money, $9,748,829,000 would be used for Salaries and Expenses (S&E) and $51,895,000 for Construction. The S&E program saw an increase of $199,673,000.
In 1896, the National Bureau of Criminal Identification was founded, providing agencies across the country with information to identify known criminals. The 1901 assassination of President William McKinley created a perception that the United States was under threat from anarchists. The Departments of Justice and Labor had been keeping records on anarchists for years, but President Theodore Roosevelt wanted more power to monitor them.
The Justice Department had been tasked with the regulation of interstate commerce since 1887, though it lacked the staff to do so. It had made little effort to relieve its staff shortage until the Oregon land fraud scandal at the turn of the 20th century. President Roosevelt instructed Attorney General Charles Bonaparte to organize an autonomous investigative service that would report only to the attorney general.
