I don’t know which side is telling the truth in the divorce between the NRA and AckMac. It could be neither of them. It could be both sides depending upon their perception of the issues.
I will note that the AckMac description of the influence on Wayne LaPierre by William Brewer III does strongly correlate with what insiders have told me. Brewer was described to have isolated LaPierre from long time friends and associates and fed his paranoia.
That said, the narrative in Ackerman McQueen’s reply and counter-claim filed on October 1st makes for interesting reading. Of particular interest are pages 19 through 42. The rest is mostly legalese. I have embedded it below. If you click on the heading, you can also download it to read later.
