On 17 December 2004, President George W. Bush signed into law the Intelligence Reform and Terrorism Prevention Act of 2004, setting in motion the largest restructuring of American intelligence in almost 60 years. Among the changes (effective on 21 April 2005) were the abolishment of the positions of Director of Central Intelligence (DCI) and Deputy Director of Central Intelligence (DDCI) that had been established under the National Security Act of 1947, and the creation of the positions of Director of National Intelligence (DNI) and Director of the Central Intelligence Agency (DCIA). The responsibilities for Intelligence Community management that the DCI used to have were given to the DNI, and the DCIA is charged with running all activities of the CIA. The DCIA is nominated by the president and confirmed by the Senate.
The position of Deputy Director of the Central Intelligence Agency (DDCIA) was established by Agency regulation after the passage of the Intelligence Reform Act in 2004. The DDCIA assists the DCIA in carrying out the duties of that position and as necessary serves as Acting DCIA. The DDCIA is selected by the DCIA.
