In 1947, the National Security Council was established to advise the President on foreign policy, along with the Central Intelligence Agency (CIA) to gather intelligence related to national security. There were concerns around having a single agency with the authority to collect, process, and evaluate secret intelligence for the President.
The CIA was established in 1947 through a bill passed by Congress that authorized it to carry out not only the explicitly stated duties but also other intelligence-related functions as directed by the National Security Council. However, this led to objections due to the standard practice of separating intelligence gathering from analysis and action.
The author talks about his books, including "Silenced, the Radio Murders", a story of three radio journalists assassinated in Miami and the subsequent investigation that uncovered a bigger conspiracy.
