President Bush travels to Tennessee today to view nuclear weapons parts turned over by Libya. The trip is seen as an effort to convince voters the Bush administration is making steady progress in the war on terrorism. Oak Ridge National Laboratory began receiving shipments from Libya in March as part of an agreement to end the country's nuclear weapons program. Bush's visit comes a week after the release of a Senate report that harshly criticized intelligence failures in the run-up to the Iraq war. The White House has suggested Bush's hardline strategy on arms proliferation and the war in Iraq helped convince Libya to abandon its nuclear ambitions. Democrats say diplomacy helped prompt the turnaround.
