In 2009, Fuller testified against Omar Khadr, recounting that he had traveled to Bagram Airbase on October 7, 2002 and showed the Canadian teenager a black-and-white photograph of Maher Arar, a Canadian who had been detained at a New York airport following a family vacation, and demanded to know if he recognised him. Khadr initially stated that he did not recognise Arar, but when further pressured by Fuller, confessed he had seen him at a Kabul safehouse run by Abu Musab al-Suri or Abu Musab al-Zarqawi. The youth's confession led to Arar's extraordinary rendition to Syria the following day, where he was tortured extensively for nearly a year before being returned to Canada, and suing both the Canadian and American governments. Fuller's testimony stirred controversy, since a Royal Commission studied the case and cleared Arar of all the American allegations.
