The National Rifle Association (NRA) is a gun rights advocacy organization originally established to promote rifle marksmanship and training for the National Guard. It has evolved into a major special interest group influencing criminal justice and gun control legislation through effective lobbying tactics and opposes federal gun-control efforts. The NRA is a vocal supporter of the Second Amendment and is known for its strong advocacy, with figures like Glenn Beck appearing and speaking at its events. The organization has faced significant internal turmoil, including executive scandals and legal challenges from state regulators over alleged financial improprieties.
