Saudi government employees were part of a support network for the 9/11 hijackers. The Obama administration should move quickly to declassify a long-secret congressional report on Saudi ties to the 2001 terrorist attack, [said former 9/11 commission member John Lehman]. The comments ... signal the first serious public split among the 10 commissioners since they issued a 2004 final report that was largely read as an exoneration of Saudi Arabia, which was home to 15 of the 19 hijackers on 9/11. The former chairman and vice-chairman of the commission [have] urged the Obama administration to be cautious about releasing the full congressional report on the Saudis and 9/11 - the 28 pages", as they are widely known in Washington. In fact, there were repeated showdowns, especially over the Saudis, between the staff and the commission's hard-charging executive director ... Philip Zelikow. Zelikow fired a staffer, who had repeatedly protested over limitations on the Saudi investigation, after she obtained a copy of the 28 pages outside of official channels. Other staffers described an angry scene late one night, near the end of the investigation, when two investigators who focused on the Saudi allegations were forced to rush back to the commission's offices after midnight after learning to their astonishment that some of the most compelling evidence about a Saudi tie to 9/11 was being edited out of the report.
