While the Downing Street Memo and the yellowcake uranium scandal lent credence to claims that intelligence was manipulated, two bipartisan investigations, one by the Senate Intelligence Committee and the other by a specially appointed Iraq Intelligence Commission chaired by Charles Robb and Laurence Silberman, found no evidence of political pressure applied to intelligence analysts. An independent assessment by the Annenberg Public Policy Center found that Bush Administration officials did misuse intelligence in their public communications. For example, Vice President Dick Cheney's September 2002 statement on Meet the Press that "we do know, with absolute certainty, that he (Saddam) is using his procurement system to acquire the equipment he needs in order to enrich uranium to build a nuclear weapon," was inconsistent with the views of the intelligence community at the time.
