Congress oversees the DNI primarily from the Senate Select Committee on Intelligence (SSCI) and the House Permanent Select Committee on Intelligence (HPSCI). These bodies, which seat 15 and 19 members respectively, determine appropriations for intelligence on a yearly basis and conduct inquiries and investigations into intelligence activities. In addition, the SSCI must approve presidential appointees including the Director of Central Intelligence, the DNI, and the Principle Deputy DNI.

DNI: Director of National Intelligence

The Office of the Director of National Intelligence (DNI) was established by the Intelligence Reform and Terrorism Prevention Act of 2004. Opened in April 2005, the office oversees 16 agencies in the intelligence community, coordinates a national strategy for Congress and the White House and controls the intelligence budget. President Bush appointed John D. Negroponte director and he serves as the president's primary intelligence briefer - a role previously held by the director of Central Intelligence.

The office of the DNI is supported by deputy directors for analysis, collection, customer outcomes and management, and by the work of the National Counterterrorism Center (NCTC), the National Counter Proliferation Center (NCPC), the National Counterintelligence Executive (NCIX) and National Intelligence Council (NIC). The NIC, which formerly reported to the Director of Central Intelligence, is the agency responsible for producing the National Intelligence Estimate.

CIA: Central Intelligence Agency

The CIA is the only member of the intelligence community that doesn't fall under the oversight of a larger cabinet seat. The CIA's focus is collecting intelligence and conducting clandestine operations for counterintelligence overseas. Its analysis is used by the military, policymakers, defense planners and law enforcement. As of June 2006, Director Gen. Michael Hayden oversaw four directorates: Intelligence, Science and Technology, Support, and the National Clandestine Service. As part of the restructuring under the Intelligence Reform and Terrorism Prevention Act of 2004, Hayden as Director reports to the DNI, John Negroponte, rather than directly to the president.
