The document discusses the origins of the Federal Bureau of Investigation (FBI). It describes how President Theodore Roosevelt pushed for expanded law enforcement powers to protect the public. This led to the creation of the Bureau of Investigation in 1908 under the Department of Justice. Congress initially resisted funding a permanent investigative force but eventually approved funds in 1909. The Bureau was granted authority to investigate a wide range of federal crimes and was tasked with enforcing laws like the Mann Act regulating prostitution.
