Ray Rice Scandal -- Ex-FBI Honcho to Probe NFL's Actions

The NFL has appointed former FBI Director Robert Mueller to run an investigation into how the league handled evidence in the Ray Rice domestic violence case.

NFL Commissioner Roger Goodell announced Mueller's probe will be overseen by Giants owner John Mara and Steelers owner Art Rooney. Goodell says Mueller will have access to all NFL records.

The announcement came hours after a league source told us ... "no one" at the NFL's various offices had received the video of Ray Rice punching his wife -- refuting an AP story that said a league exec was sent the clip back in April.
