Col. Oliver North, the president of the National Rifle Association, will leave his position at the end of his term.

North has decided he will not seek a second term, according to a Saturday report from the Associated Press.

NRA CEO Wayne LaPierre accused North of “backroom” blackmailing him in a letter sent out Thursday to NRA board members.

The NRA, led by LaPierre, had filed a lawsuit against its longtime public relations firm Ackerman McQueen this month.

LaPierre alleged in the letter that North had teamed up with Ackerman McQueen to release a letter with damning information against him and two other members of the NRA executive team if LaPierre did not resign immediately.

LaPierre said in the letter that he would “not back down” or be intimidated by North’s alleged threats.

North’s public profile rose after his defense of President Reagan’s administration during the Iran-Contra affair, where the U.S. sold weapons to Iran, purportedly for the release of American hostages in Lebanon and despite the U.S. having Iran under an arms embargo, but used the money to fund the rebel Contras in Nicaragua.

North, then a part of the National Security Council staff, came before Congress to testify on the brewing scandal.

He was later convicted for destroying government documents, accepting an illegal gratuity, and obstructing Congress. He ultimately had his sentence vacated.

Typically, the NRA president has been seen as a ceremonial position with the position changing every year or every couple of years.

The NRA board is set to meet Monday where they will likely take up the issue of finding a successor to North.
