White House: Evidence of chemical arms in Syria not 'airtight'

The White House said on Friday it continues to study evidence that the Syrian government has used chemical weapons and would not set a timetable for corroborating reports.

"I'm not going to set a timeline, because the facts need to be what drives this investigation, not a deadline," White House spokesman Jay Carney told reporters at a briefing. "We are continuing to work to build on the assessments made by the intelligence community, that the degrees of confidence here are varying, that this is not an airtight case," he said. (Reuters)
