Barack Obama actually said...

"Terrorist use of weapons of mass destruction, especially nuclear weapons, is indeed the gravest security threat we face today."

"The President-elect and I are both strongly committed to Senate approval of the CTBT and to launching a diplomatic effort."

"The President-elect made it clear during the campaign that he supports the negotiation of a treaty banning the production of fissile material for use in nuclear weapons."

"President-elect Obama and I strongly supported legislation providing $50 million to the IAEA for the creation of an international nuclear fuel bank."
