WASHINGTON (CNN) -- Sen. Lindsey Graham, a vocal supporter of President Bush's plan to increase troops in Iraq, urged his colleagues Wednesday not to support a non-binding resolution that condemns the policy, telling CNN such a measure will have dire consequences.

"The worst thing you could do is allow this commander to go off to a new fight with a new mission and make a political statement you think he's going to lose," The South Carolina Republican told CNN's Wolf Blitzer. "I will not stand for that."

Graham also reacted to Arlen Specter's comments yesterday to CNN in which the Pennsylvania Republican said he had never seen "such emotion and such concern" amongst the GOP caucus.

"It undercuts our ability to be successful, emboldens our enemy, so there's a lot of emotion," the senator said. "We paid a heavy price for our mistakes. I'm trying not to compound them."
