Pelosi and Torture
by John Nichols
That House Speaker Nancy Pelosi has been a disappointing leader for House Democrats, few serious observers of the congressional condition will deny. But, now, she appears to be something more troubling: a serious hindrance to the fight against the use of crudest and most objectionable torture techniques.
Democrats and Republicans with a conscience have gotten a good deal of traction in recent months in their battle to identify the use by U.S. interrogators of waterboarding - a technique that simulates drowning in order to cause extreme mental distress to prisoners — as what it is: torture. Arizona Senator John McCain, a GOP presidential contender, has been particularly powerful in his denunciations of this barbarous endeavor. And Senate Intelligence Committee chair Jay Rockefeller, D-West Virginia, and key members of the Senate Judiciary Committee have effectively pressed the issue on a number of fronts.
Now, however, comes the news that Pelosi knew as early as 2002 that the U.S. was using waterboarding and other torture techniques and, far from objecting, appears to have cheered the tactics on.
The Washington Post reports that Pelosi, who was then a senior member of the House Intelligence Committee, was were informed by CIA officials at a secret briefing in September 2002, that waterboarding and other forms of torture were being used on suspected al-Queda operatives. That’s bad. Even worse is the revelation that Pelosi was apparently supportive of the initiative.
