US says would provide legal justification for Syria action

The United States would provide its own legal justification for an eventual response to chemical weapons use in Syria if necessary once President Barack Obama decides how to proceed, the White House said on Thursday.

"When the president reaches a determination about the appropriate response ... and a legal justification is required to substantiate or to back up that decision, we'll produce one on our own," White House spokesman Josh Earnest told a briefing. (Reuters)
