"The fact is that you gave evidence to Congress claiming that Gallup had found "a large majority of the Arab world" who believed the September 11 attacks "were the work of the United States government itself and/or a Jewish conspiracy". What you said is untrue, and Gallup has confirmed that. I trust you will now apologise to Congress for your false testimony. Finally, in the light of your most recent remarks about me personally, I will make clear now that your nationality and religion do not bother me in the slightest. What does concern me is your political agenda, and the deceitful way you go about promoting it."
