“I strongly believe that a response to this action must not be a unilateral military intervention,” Baldwin said. “It’s not our responsibility alone … which is why I oppose military involvement in Syria.”

President Obama has asked for congressional support to use limited military strikes against Syrian President Bashar Assad, who is accused of using chemical weapons against his own people. The Senate Foreign Relation Committee passed on a bipartisan 10-7 vote S.J.Res. 21, which would authorize a limited 60-day strike.

Obama will address the nation Tuesday evening as new possibilities about a negotiated settlement with Syria is slowing congressional action.

On Monday, Russia suggested an agreement under which Syria would give up control of its chemical weapons, and Syria indicated it could agree to this solution. That prompted Obama to acknowledge that this sort of agreement could allow Syria to dodge a U.S. attack.

Lawmakers are now working on a new resolution that would authorize military action only if Syria refuses to relinquish its stockpile of chemical weapons to international control. 

Although Baldwin did not mention opposition to any particular resolution she stated she opposed all effort to go to war in Syria.
