In a previously undisclosed private memo, President Obama's intelligence director told colleagues that enhanced interrogation techniques used by the Bush administration yielded important information that helped America deal with the threat of terrorism.

"High value information came from interrogations in which those methods were used and provided a deeper understanding of the al Qa'ida organization that was attacking this country," the Director of National Intelligence, retired Admiral Dennis Blair, told colleagues in the two-page memo April 16.

That sentence was not included in a shorter one-page statement Blair's office gave to the media last Thursday, the same day Obama released previously top secret Bush administration memos laying out Republican lawyers' rationale for why they believed the interrogations were legal. Obama officially banned the techniques during his first week in office, with his aides charging it amounted to illegal torture.
