Waterboarding is a controversial interrogation method where the individual is usually immobilized, then water is poured over his or her face to simulate drowning. Waterboarding elicits the gag reflex and can make the subject believe his or her death is imminent while not causing physical evidence of torture.

A debate began in late 2007 over whether waterboarding should be officially considered torture, after it had been revealed that the CIA had used the practice as recently as 2005. The practice was banned by the U.S. Military in 2006, however the military rules do not cover the CIA.

In February 2008, the U.S. Congress passed a bill to ban the practice, however President Bush vetoed the bill in March 2008.
