[Patrick Appel] Huckabee made this statement:
I’m finding just out how long I can go sleep deprived. You know, running for office is sort of like being waterboarded, I think.
And here is a description of Al-Kahtani's interrogation from a 2006 Atlantic article:
Al-Kahtani was interrogated for 18 to 20 hours a day for 48 of 54 days; he had water dripped on his head and was blasted with cold air-conditioning and loud music to keep him awake; his beard and head were shaved; he was forced to wear a bra and panties and to dance with a male jailer; he was hooded; he was menaced with a dog, told to bark like one and led around on a leash; he was pumped full of intravenous fluids and forced to urinate on himself; he was straddled by a female interrogator and stripped naked; and more -- all under a list of interrogation methods personally approved by Rumsfeld.
I should note that Huckabee isn't the first to joke about waterboarding. Giuliani made similar statements when he was still running.
