Former secretary of state Hillary Rodham Clinton backs President Obama’s call for Congress to authorize military action against Syria, a Clinton adviser said Tuesday.

"Clinton supports the president's effort to enlist the Congress in pursuing a strong and targeted response to the Assad regime's horrific use of chemical weapons,” the adviser said in a statement.

It was the first comment from the former secretary of state on Syria in the wake of the chemical weapons attack there and the president’s decision to put military action on hold for now while asking for Congress to give him the authority to launch a retaliatory attack.

Clinton has long been a proponent of a more vigorous U.S. response to the civil war in Syria. As a member of the administration, she argued in favor of doing more to arm and assist rebel forces.

Clinton is scheduled to deliver a speech next week on the controversy over the National Security Agency’s surveillance program. The setting could give her a forum to offer additional comments on the Syrian situation and the congressional debate now underway.
