The Bush Administration's prewar claims that Saddam Hussein had weapons of mass destruction were "manipulated, at least" to mislead the American people, former President Jimmy Carter said Wednesday. The decision to go to war was the culmination of a long-term plan to attack Iraq that resulted from the first President Bush not taking out Saddam, Carter said on NBC's "Today" show. Carter also said he supports the move by Senate Democrats to force an update on the investigation into prewar intelligence on Iraq, and says Republicans have been dragging their feet on the investigation. Democrats Tuesday used a rarely invoked Senate rule to force a secret session as a way to dramatize their assertions that the Bush administration misused intelligence in the run-up to the war in Iraq. A bipartisan committee has been appointed to review the investigation.
