A former member of the 9/11 Commission on Tuesday left open the possibility that the Saudi royal family knew about the 9/11 terror plot before it happened.

Rep. Dana Rohrabacher, R-Calif., asked members of the panel at a House Foreign Relations subcommittee hearing to raise their hands in response to this question:

“How many of you there believe that the royal family of Saudi Arabia did not know and was unaware that there was a terrorist plot being implemented that would result in a historic terrorist attack in the United States, in the lead-up to 9/11?”

Two of the four panelists raised their hands, but Tim Roemer, 9/11 Commission member and a former congressman from Indiana, did not. Neither did Simon Henderson, director of the Gulf and Energy Policy Program at the Washington Institute for Near East Policy.

“Congressman, that is just too difficult a question for someone to raise their hand or put their hand down,” Roemer explained. He then suggested that Rohrabacher read 28 classified pages of a 2002 congressional report that describe overseas support for the 9/11 attackers.
