(CN) - President Barack Obama acknowledged on Aug. 1 this year, "We tortured some folks," but a glimpse into that remark is finally available with the declassification Tuesday of a heavily redacted summary of a report by the Senate Select Committee on Intelligence (SSCI).
One passage of the 524-page summary describes how the alleged "mastermind" of the U.S.S. Cole bombing, Abd al-Rahim al-Nashiri, "launched a short-lived hunger strike that resulted in the CIA force feeding him rectally."
Accused Sept. 11, 2001, mastermind Khalid Sheikh Mohammed, who was waterboarded 183 times, also endured "rectal hydration" in an effort to exert "total control over the detainee," the report stated.
But the repeated waterboarding sessions produced "significantly fabricated information" from Mohammed, the committee found.
Meanwhile a footnote notes one CIA interrogator's finding that an Afghanistan detainee Gul Rahman who died in the Salt Pit "literally looked like a dog that had been kenneled."
During another waterboarding session, Guantanamo detainee Abu Zubaydah became "completely unresponsive, with bubbles rising through his open, full mouth," the report says. The CIA admittedly destroyed Zubaydah's interrogation tapes nearly a decade ago.
It has been roughly eight months since Sen. Dianne Feinstein, the California Democrat who chairs SSCI, announced that the committee voted to release a portion of the report produced from the review of 6 million classified documents between 2009 and 2013.
"The report exposes brutality that stands in stark contrast to our values as a nation," Feinstein said earlier this year. "It chronicles a stain on our history that must never again be allowed to happen. This is not what Americans do."
As she took to the Senate floor on Tuesday, Feinstein called this history "a stain on our values."
Tuesday's summary says that the "brutal" methods were "far worse than the CIA represented to policymakers and others."
Sleep deprivation sessions lasted "for up to 180 hours, usually standing or in stress positions, at times with their hands shackled above their heads," it continues.
"At least five detainees experienced disturbing hallucinations during prolonged sleep deprivation and, in at least two of those cases, the CIA nonetheless continued the sleep deprivation," the summary also states.
An image of a detainee being "clothed in a diaper, and forced to go to the bathroom on himself" appears in the summary as well.
One section of the summary describes how the hunger strike of "high-value detainee" Majid Khan led interrogators to serve him a "lunch tray" consisting of a "pureed" mixture of hummus, pasta with sauce, nuts, and raisins that was "rectally infused."
The Pakistani, who allegedly tried to cut his wrists twice after multiple feedings, pleaded guilty six years later to planning terrorist attacks at a military commission.
He will reportedly will testify in the trial of Mohammed, the alleged 9/11 "mastermind."
The black lines that pockmark SSCI's document reflect the months the White House and the CIA spent scrubbing both the names and the pseudonyms of every case agent that participated in the so-called "enhanced interrogation techniques" that the report concluded were "ineffective."
Referring to this wait, Feinstein announced on the Senate floor: "This report is too important to shelve indefinitely."
The nightmarish summary, amounting to less than a tenth of the 6,200-page report, cost the U.S. government roughly $40 million to produce.
