Pretty sure Giancana gave nothing to Aiuppa who was very close to Joe Batters. Joey was established long before Giancana was a twinkle in Accardos eye. I'd be surprised if Momo was even included in board meetings with Accardo, Ricca, Aiuppa,LaPorte and other lower profile guys.Giancana was the face of the outfit but I don't believe he had any power. The only reason Aiuppa took over was all the other guys they put in either died or screwed up like Giancana. Aiuppa always had more power than Giancana.
