republican senator lindsey graham and north dakota democrat kent conrad rejected claims by the libyan government that the saturday airstrike was an assassination attempt. >> in my view, wherever gaddafi goes is a legitimate military target. the commander and control source, not the legitimate leader of libya. and the way to get this to end is to go after the people around him. and his support network. i support what nato is doing and i'd like to have a pour it own approach to get it over with. >> i think you go after the pillars of his power. the pillars of his pow rer the regimens controlled by his sons, the mercenaries he has brought in from other countrys, his money. and his tribe. >> nato has pledged to step up its airstrikes, especially on gaddafi's commander and control. jamie? >> jamie: doug mckelway live in washington. thanks.
