A probe looking at the effectiveness of harsh interrogation techniques in the United States military is expected to conclude that the methods didn’t produce breakthroughs.

Democrats from the Senate Intelligence Committee have spent three years examining records charting daily operations of investigations to disprove claims by Bush supporters that waterboarding, sleep deprivation, and other tactics led to counterterrorism coups. The CIA had began starting to pull back from these techniques before Obama banned them upon taking office.
