US Secretary of State John Kerry has said that he does not believe that Congress will "turn it's back" America's credibility in its response to the chemical weapons attack in Syria.
In an interview with NBC, he said: "The United States is strongest when Congress speaks with the President, when the American people are invested, because we have had an appropriate vetting of all the facts.
"I don't believe my former colleagues in the United States Senate, in the House, will turn their backs on all of our interests."
