Syria's Chemical Attack in Damascus

CNN's John Defterios responds to British diplomat Thomas Phipps' claim that Syria was guilty of a chemical attack in GUTA in 2013. He says the allegation is contested by leaks from inside the U.S., where Obama administration officials back when Obama was considering bombing Syria, said it wasn't a slam dunk. The intelligence about Assad's supposed guilt "was just not there," according to James Clapper, director of national intelligence under Obama.
