McCaskill wouldn't 'rule out' U.S. troops in Syria if 'absolutely necessary'
U.S. Sen. Claire McCaskill said Sunday that she would not rule out the possibility of U.S. troops in Syria, but only if deemed "absolutely necessary." On CBS’ "Face the Nation," McCaskill also said she had not yet seen “a conclusive chain of evidence” to prove who exactly ordered the use of sarin gas in the Syrian civil war.
