The National Rifle Association is backing Democratic Attorney General Chris Koster for Missouri governor.

The NRA's political action committee on Tuesday announced it endorsed Koster over his Republican opponent Eric Greitens.

Greitens is a former Navy SEAL officer and former Democrat. His campaign manager says "no one is stronger" than Greitens on Second Amendment issues.

Koster, a former Republican, is the only Democratic statewide candidate in Missouri the NRA endorsed.

The endorsement is the latest of several that typically go to Republican candidates but that have instead gone to Koster this year.

He also won the Missouri Farm Bureau and other top agricultural groups' support.

Greitens, a first-time candidate, also failed to get an endorsement from Missouri Right to Life's political action committee.
