The Presidential comment probably won't cause him much grief since "a few weeks ago" from May 3, and the President's comment in March is really not a major time difference. Sloppy; but not huge. However, the original DOJ stonewall of Congress back in January was that DOJ's IG was conducting its own investigation and that they couldn't jeapordize that investigation. That one is going to be tougher to explain.
That is a first class observation that a lot of us have overlooked --- like not seeing the forest for the trees.
Say what you will about Janet Reno, at least she stood up and took responsibility for ordering the feds to storm the Branch Davidian compound at Waco.
