Deep state conspiracy theory in the United States

In the United States, a political conspiracy theory posits the existence of a deep state within the US federal government, primarily composed of members of the FBI and CIA. Proponents argue that a clandestine network of conspirators within the leadership of the financial and industrial sectors exercise power alongside or within the elected government. There have been precursors to the idea of a deep state conspiracy since at least the 1950s.
