After Charles Duelfer took over from Kay in January 2004, Kay said at a Senate hearing that "we were almost all wrong" about Iraq having stockpiles of weapons of mass destruction, but that the other ISG findings made Iraq potentially "more dangerous" than was thought before the war. In an interview, Kay said that "a lot" of the former Iraqi government's weapons of mass destruction program had been moved to Syria shortly before the 2003 invasion, albeit not including large stockpiles of weapons.
