He testified that he paid Frank Calabrese street tax on his book.

Also, another thing worth noting on Family Secrets convictions:

The other lawyers all blamed Frank Calabrese's testimony for sinking everyone else. Apparently he came off so miserably and there was so much evidence against him that they all felt it greatly diminshed their chances at an acquittal.

Lombardo for instance had offered to surrender as long as he was guaranteed a separate trial; of course the feds told him to pound dirt.

Who knows if Marcello and Lombardo would have been convicted if they had all had separate trials. It probably would have greatly increased the odds of acquittal though.
