The NFL called in a former FBI director to examine how it pursued and handled evidence in the Ray Rice domestic violence case as pressure increased for the league to be more transparent about its original investigation.

The move late Wednesday came hours after The Associated Press reported that a law enforcement officer said he sent an NFL executive a video in April that showed Rice striking his then-fiancee at a casino. Goodell has maintained that no one in the NFL saw the video until it was released by TMZ Sports Monday.

Women's organizations, members of Congress and players have called for more detail about the NFL's handling of the Rice case. The criticism intensified after the law enforcement official's account.
