The 9-11 staffer who was given the information about Able Danger and Atta was Philip Zelikow. According to the 9-11 Commission Report (page xiii), he was the Executive Director of the Commission staffers. In other words, it sounds like he was the head staffer.

Information about Philip Zelikow.
Commission leaders Thomas H. Kean (R) and Lee H. Hamilton (D) said in the joint statement that panel staff members have found no documents or other witnesses to back up claims made by a U.S. Navy officer, who told the commission staff in July 2004 that he recalled seeing Atta's name and photograph on a chart prepared by another officer.
They are accusing this U S Navy officer of lying before the committe----what did they do about it?!!!
We also found sourcing the other day that Gorelick was in charge of culling through the information that came in and deciding whether the full commission would have access or not.
Whether she was involved in hearing about Able Danger, I don't know. She may not have wanted her fingerprints on it, knowing full well that they tried to tell the FBI in 1999 and again in 2000 about Atta and it is her Wall which prevented action.
