WASHINGTON (AP) -- Secretary of State John Kerry asserted Sunday on CBS "Face the Nation" 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 show 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.
Kerry also said he was confident that Congress will give Obama its backing for an attack against Syria, but the former Massachusetts senator also said the president has authority to act on his own if Congress doesn't give its approval.
