Approval of clandestine and covert operations came from a variety of committees, although in the early days of quasi-autonomous offices and the early DDP, there was more internal authority to approve operations. After its creation in the Truman administration, the CIA was, initially, the financial manager for OPC and OSO, authorized to handle "unvouchered funds" by National Security Council document 4-A of December 1947, the launching of peacetime covert action operations. NSC 4-A made the Director of Central Intelligence responsible for psychological warfare, establishing at the same time the principle that covert action was an exclusively Executive Branch function.
