Pryor is up for re-election in 2014. His Republican opponent, Rep. Tom Cotton, supports the intervention.
Read the senator's full statement:
The decision to use military force is one of the gravest responsibilities Members of Congress face, and it is one that I take very seriously. I have heard presentations and testimonies from the Administration on their case for military action, have read and studied the text of the authorization for the use of military force that will come before the Senate next week, and have listened to the concerns of thousands of Arkansans as I have traveled the state.
I have said, before any military action in Syria is taken, the Administration must prove a compelling national security interest, clearly define a mission that has a definitive end-state, and then build a true coalition of allies that would actively participate in any action we take. Based on the information presented to me and the evidence I have gathered, I do not believe these criteria have been met, and I cannot support military action against Syria at this time.
