In a potentially devastating blow for Roger Goodell, a law enforcement official claims he sent a video of Ray Rice punching his then-fiancee to an NFL executive five months ago - completely contradicting the commissioners claim that no one at the NFL had seen it before Monday. The person played The Associated Press a 12-second voicemail received from from an NFL office number on April 9 confirming the video arrived. A female voice expresses thanks for the video and says: 'You're right. It's terrible.' And in a sign the NFL is descending into full damage limitation mode, Goodell announced former FBI director Robert S. Mueller III will conduct a probe into how the league pursued and handled evidence as it investigated claims against Rice.
