U.S. Deputy Director of Central Intelligence John E. McLaughlin speaks at a press conference at the Central Intelligence Agency headquarters in Langley, Virginia July 9, 2004. U.S. intelligence agencies overstated the threat of Iraqi weapons of mass destruction, relied on dubious sources and ignored contrary evidence in the run-up to the 2003 U.S. invasion of Iraq, a Senate committee reported on Friday. McLaughlin, who will replace George Tenet as acting CIA director, said the Senate panel spent nearly a year essentially dissecting one intelligence report. Tenet, who reportedly told Bush it was a "slam dunk" that Iraq had such weapons before the war, announced his resignation last month and will step down on Sunday. REUTERS/Shaun Heasley SH/GN/SN
