Democrats and Republicans disagree about whether brutal interrogation by the CIA produced valuable intelligence after 911. Today, White House Press Secretary Josh Earnest reiterated the President's view that "these techniques, regardless of whether or not they elicit national intelligence information, undermines our ability to use this very powerful tool." But outgoing Democratic Senator Mark Udall of Colorado countered, that "while the study clearly shows that the CIA's detention interrogation program itself was deeply flawed, the deeper, more endemic problem lies in a CIA assisted by a White House that continues to try to cover up the truth."
