President Obama tells CNN that the United States must keep up pressure on Syrian President Bashar al-Assad, but he's leaving the door open to averting a strike.
Secretary of State John Kerry provided a new possibility of a diplomatic deal when asked whether there was anything al-Assad's government could do or offer that would stop an attack, Kerry said that al-Assad "could turn over every single bit of his chemical weapons to the international community in the next week."
Kerry then tried to walk that proposal back, saying it was rhetorical. But France, Russia and Syria all jumped on it, and it's gaining a lot of momentum.
Assad also appeared on television - defiant, warning America of retaliation if there's a strike.
