Mr. Gibson lost his right to own guns after his conviction in 2011. Federal law prohibits all those with felony convictions, and those with certain domestic violence misdemeanors, from possessing guns.

The "Lethal Weapon" star lost his firearm rights as a result of a 2011 domestic violence conviction. A former Department of Justice employee says that a dispute over Mel Gibson and lethal weapons led to her firing.

Elizabeth G. Oyer, the former U.S. pardon attorney, reportedly says she was fired after she opposed restoring Mel Gibson's gun rights.
