Enhanced interrogation techniques or alternative set of procedures are terms that describe a George W. Bush administration authorization and use of certain severe interrogation methods including hypothermia, stress positions and waterboarding. These techniques were used by the Central Intelligence Agency (CIA) and the Department of Defense (DoD) in secret prisons, the Guantanamo Bay detention camps and Abu Ghraib on untold thousands of prisoners after the September 11 attacks in 2001 including notably Khalid Shaikh Mohammed, Abu Zubaydah and Mohammed al-Qahtani.

Debates arose over the legality of the techniques—whether or not they had violated U.S. or international law or whether they constitute torture. The CIA destroyed many videotapes depicting prisoners being interrogated saying that what they showed was so horrific they would be "devastating to the CIA," and that "the heat from destroying is nothing compared to what it would be if the tapes ever got into public domain." The United Nations special rapporteur on torture, Juan Mendez firmly stated that waterboarding is torture — “immoral and illegal.” and in 2008, fifty-six House Democrats asked for an independent investigation.

Interrogation (also called questioning or interpellation) is interviewing as commonly employed by officers of the police, military, and Intelligence agencies with the goal of extracting a confession or obtaining information. Subjects of interrogation are often the suspects, victims, or witnesses of a crime. Interrogation may involve a diverse array of techniques, ranging from developing a rapport with the subject to outright torture.

There are multiple techniques employed in interrogation including deception, torture, increasing suggestibility, and the use of mind-altering drugs.

A person's suggestibility is how willing they are to accept and act on suggestions by others. Interrogators seek to increase a subject's suggestibility. Methods used to increase suggestibility may include moderate sleep deprivation, exposure to constant white noise, and using GABAergic drugs such as sodium amytal or sodium thiopental. It should be noted that attempting to increase a subject's suggestibility through theses methods may violate local and national laws concerning the treatment of detainees, and in some areas may be considered torture. Sleep deprivation, exposure to white noise, and the use of drugs may greatly inhibit a detainee's ability to provide truthful and accurate information.

Richard Bruce "Dick" Cheney (born January 30, 1941) served as the 46th Vice President of the United States (2001–2009), under George W. Bush.

Born in Lincoln, Nebraska, Cheney was primarily raised in Sumner, Nebraska, and Casper, Wyoming. He began his political career as an intern for Congressman William A. Steiger, eventually working his way into the White House during the Nixon and Ford administrations, where he served the latter as White House Chief of Staff. In 1978, Cheney was elected to the U.S. House of Representatives from Wyoming; he was reelected five times, eventually becoming House Minority Whip. Cheney was selected to be the Secretary of Defense during the presidency of George H. W. Bush, holding the position for the majority of Bush's term. During this time, Cheney oversaw the 1991 Operation Desert Storm, among other actions.

Out of office during the Clinton presidency, Cheney was chairman and CEO of Halliburton Company from 1995 to 2000.

Cheney was born in Lincoln, Nebraska, the son of Marjorie Lorraine (née Dickey) and Richard Herbert Cheney. He is of predominantly English, as well as Welsh, Irish, and French Huguenot, ancestry; Cheney's 8th great-grandfather, William Cheney, immigrated from England to Massachusetts in the 17th century. Although not a direct descendant, he is collaterally related to Benjamin Pierce Cheney (1815–1895), the early American expressman. Cheney is a very distant cousin of both Harry S. Truman and Barack Obama; the three share a common ancestor in Mareen Duvall, a Huguenot who fled from France to England in the 17th century and later settled in Maryland. His father was a soil conservation agent for the U.S. Department of Agriculture and his mother was a softball star in the 1930s; Cheney was one of three children.

Donald Henry Rumsfeld (born July 9, 1932) is an American politician and businessman. Rumsfeld served as the 13th Secretary of Defense from 1975 to 1977 under President Gerald Ford, and as the 21st Secretary of Defense from 2001 to 2006 under President George W. Bush. He is both the youngest and the oldest person to have served as Secretary of Defense. Additionally, Rumsfeld was a four-term U.S. Congressman from Illinois (1962–1969), Director of the Office of Economic Opportunity (1969–1970), Counsellor to the President (1969–1973), the United States Permanent Representative to NATO (1973–1974), and White House Chief of Staff (1974–1975).

Born in Illinois, Rumsfeld attended Princeton University, graduating in 1954 with a degree in political science. After serving in the Navy for three years, he mounted a campaign for Congress in Illinois' 13th Congressional District, winning in 1962 at the age of 30. Reelected four times, he was a leading co-sponsor of the Freedom of Information Act. Rumsfeld was reluctantly appointed by President Richard Nixon to head the Office of Economic Opportunity in 1969; appointed Counselor by Nixon and entitled to Cabinet-level status, he would also head up the Economic Stabilization Program before being appointed Ambassador to NATO. Called back to Washington in August 1974, Rumsfeld was appointed Chief of Staff by President Ford, recruiting a young one-time staffer of his, Dick Cheney, to succeed him when Ford nominated Rumsfeld Secretary of Defense in 1975.

Ronald Ernest "Ron" Paul (born August 20, 1935) is an American politician who has been the U.S. Representative for Texas's 14th congressional district, which includes Galveston, since 1997, and a three-time candidate for President of the United States, as a Libertarian in 1988 and as a Republican in 2008 and currently 2012. He is an outspoken critic of American foreign and monetary policies, including the Military–industrial complex and the Federal Reserve, and is known for his libertarian-leaning views, often differing from his own party on certain issues.

A native of Pittsburgh, Pennsylvania, Paul is a graduate of Gettysburg College and Duke University School of Medicine, where he earned his medical degree. He served as a medical officer in the United States Air Force from 1963 until 1968. He worked as an obstetrician-gynecologist from the 1960s to the 1980s, delivering more than 4,000 babies. He became the first Representative in history to serve concurrently with a child in the Senate when his son Rand Paul was elected to the United States Senate for Kentucky in 2010.
