Portland Imam Mohamed Sheikh Abdirahman Kariye leaves the United Sates Court of Appeals following oral arguments on the ACLU No Fly List challenge Friday, May 11, 2012, in Portland, Ore. A federal appeals court in Oregon will hear arguments in a lawsuit filed by 15 men who say their rights were violated because they are on the U.S. government's no-fly list. They are asking the 9th U.S. Circuit Court of Appeals in Portland to order their removal from the list or at least get an explanation why they were put on it. The plaintiffs include the imam of a Portland mosque and a Marine veteran who is the son of a Palestinian immigrant. Others are outside the country and unable to return. (AP Photo/Rick Bowmer)
