He has been placed at the meeting. My info is that it was at that meeting where he resigned his leadership position. I presume that he voted no, but he the duty to report the conspiracy to the FBI.
It must also be noted that Kerry initially LIED about the date of his supposed resignation from the VVAW. Until he was forced to fess up to his attendance at the Kansas City "Assassination" meeting, Kerry (and his campaign) were peddling the outright LIE that Kerry recalled resigning from VVAW in a St. Louis VVAW meeting in July, 1971.
His campaign was FORCED to acknowledge Kerry's fraudulent "memory" when FBI surveillance files (and, subsequently, eyewitnesses from within the VVAW itself) placed him at the meeting of the VVAW conspirators.
Ironically (if my memory serves me correctly), the FBI "Gotcha" was served up by Gerald? Nicosia, a Kerry supporter who had been doing pro-Kerry research when he stumbled into the FBI revelation. As I also recall, Nicosia was stunned by the information he had discovered.
Apparently not so Mr. Sanders or the MSM who give wide latitude to associating with assassination conspirators and documented, outright LIARS like Kerry.
