The NFL says former FBI director Robert S. Mueller III will conduct a probe into how the NFL handled evidence as it investigated domestic violence claims against former Ravens running back Ray Rice.
NFL spokesman Greg Aiello said in a statement Wednesday that the investigation will be overseen by NFL owners John Mara of the New York Giants and Art Rooney of the Pittsburgh Steelers.
NFL Commissioner Roger Goodell will grant Mueller access to all NFL records, the statement said.
The NFL's announcement came after a law enforcement official told the AP on condition of anonymity that he sent a tape of Rice striking his then-fiancee at a casino to an NFL executive in April. Goodell has maintained that no one at the league had seen the tape prior to Monday, when it went viral online.
