Answer:
The Federal Bureau of Investigation (FBI) has a similar role at the national level.
Explanation:
The Federal Bureau of Investigation was established in 1908, and in today's date serves as the paramount law enforcement agency in the United States. It functions directly under the supervision of the Department of Justice of the federal government. All the states in the United States of America come under the jurisdiction of the FBI irrespective of which political parties are running the state and the local governments.
The FBI is authorized to carry out investigations in over 200 types of federal crimes throughout the United States. Some of these crimes are counterintelligence, terrorism (both domestic and international), cybercrime, narcotics and allied crimes, crimes pertaining to the breach of civil rights, etc. It has around 56 field offices in all the important cities all over the United States and more than 400 resident agencies in other cities that are comparatively smaller yet sensitive.
The FBI also has offices at various US Consulates and embassies outside the international boundaries of the United States. These offices function in order to provide intelligent feeds to other anti-terrorist agencies across the globe but are not authorized to carry out unilateral operations on foreign lands.
