I'm listening to one of the convicted members of the Reagan administration explain what he did on C-SPAN Radio. It's a couple of Reagan sycophants doing the interview, but the guy seems relatively honest. A (mob related) "maritime union" "helped" with passing the first tax increase after Reagan's massive 1981 tax cut, called TEFRA. The "maritime union" helped get it passed. The convicted guy wrote Ed Meese, then Attorney General, saying how the "maritime union" should be helped out, since friends should be helped.
Google searches for "Reagan 'maritime union' TEFRA conviction" and "Reagan mob TEFRA conviction" yield no results.
Based on interviews with Gerald Strober and Deborah Hart Strober.
