The lawyers also said their case is boosted by sworn statements by 9/11 Commissioners John Lehman and Bob Kerrey, as well as Bob Graham, co-chairman of the Joint Congressional Inquiry into 9/11. Graham says he believes "there was a direct line" between some Sept. 11 terrorists and the government of Saudi Arabia while Lehman, a former Navy secretary, explained close historical ties between the kingdom's government clerics and al-Qaida, the lawyers noted.
