If you haven’t yet read about the horrifying descriptions of “Enhanced Interrogation Techniques” detailed in the Senate Intelligence Committee’s report on torture, do so. The 525-page document describes a program that relied on detainee abuse (including sleep deprivation, stress positions, force-feedings and solitary confinement), impunity and secrecy—and that lasted for years.

Jon Stewart devoted last night’s opening segment to the “deluge of depravity” revealed in the report. Not only did the CIA torture detainees, but officials in the Senate and White House were fully aware of the extent of the program. Though Stewart reserves his most biting comments for President Bush, who for years insisted that the U.S. “doesn’t torture,” he saves some for President Obama, whose administration has refused to release thousands of top-secret documents requested by the committee.

After criticizing Obama for breaking his promise to be more transparent than his predecessor, he quipped, “To be fair to the president, he was great on Colbert last night.”
