In a December 2008 interview with the New York Times, Kadi added that he once met Osama bin Laden in Chicago. He gives the date as 1981.[40] Steven Coll, a biographer of the Bin Laden family[41] discovered that the date of the visit was 1979. Osama "was here for two weeks in 1979, it seems, and he visited Los Angeles and Indiana, among other places."[42]
