Edgar Hoover, at President Franklin Roosevelt's direction, added to the FBI's duties investigation of possible espionage, sabotage, or subversion. After the war, foreign intelligence duties were assigned to the newly established Central Intelligence Agency. The CIA was expressly precluded from engaging in domestic law enforcement activities.' Domestic intelligence responsibilities remained with the FBI. J SO U.S. c. §§ 1801 et seq. As enacted in 1978, fISA permitted orders authorizing electronic surveillance. It did not refer to physical searches. In 1994, the statute was amended to permit orders authorizing physical searches. Pub. L. No. 103-359,108 Stet. 3423,3443 (Oct. 14,1994); 50 U.S.C. §§ 1821·1829. 2 See, The National Security Act of J 947 (SO U.S.C. 403·3(d)(l») (the CIA "shall have no police, subpoena, or law enforcement powers or internal security functions).
