No effects

From the Washington Post:

"White House officials jumped into action, but the commission was skeptical about whether their efforts that morning had much effect. It said a video teleconference in the White House situation room, chaired by Richard A. Clarke, then head of counterterrorism at the White House, "had no immediate effect on the emergency defense efforts."

Surprise, surpise....as usual things would have come down to people on the ground.
