Kerry: US has evidence sarin gas was used in Syria
Secretary of State John Kerry asserted Sunday that the United States now has evidence of sarin gas use in Syria and said "the case gets stronger by the day" for a military attack.
A day after President Barack Obama stepped back from his threat to launch an attack, Kerry said in a series of interviews on the Sunday news shows that the administration learned of the sarin use within the past 24 hours through samples of hair and blood provided to Washington by first responders in Damascus.
