During the Castellamarese war, there was a attempt made on Carlo Gambino's brother by Maranzano guys. i suspect Bonanno could've been involved, this left some bad blood with Gambino.
on Bonanno's side, Joe slightly supported Gambino at a commission meeting after Anastasia was clipped against Albert's loyalist Tommy Rava and Neil Dellacroce. then Gambino used his power with Luchesse against him.
