An investigation has been opened into how the NFL handled the incident of Baltimore Ravens' Ray Rice hitting his then-fiancee in an elevator and how much they knew. USA Today Sports Columnist Christine Brennan shares more.

The NFL has opened an investigation into how the league handled the Ray Rice domestic violence incident.

Former FBI director Robert S. Mueller will lead the investigation and NFL owners John Mara of the New York Giants and Art Rooney of the Pittsburgh Steelers will oversee it.

The big question is whether or not league officials saw the elevator video that captured Rice hitting his then-fiancee, who is now his wife.

NFL commissioner Roger Goodell claims he asked for the tape multiple times and did not receive it or see the footage of inside the elevator until Monday, USA Today reports.

For more on how this will play out, USA Today Sports Columnist Christine Brennan weighs in.
