There’s a reason why Sammy doesn’t like Michael.

In an interview, Franzese says Gotti on his worse day is still a better person than Sammy.

Then he started saying how he doesn’t approve of governments making deals with a self confessed murderer with 19 under his belt. Michael did say it’s nothing personal

Also Michael doesn’t buy the Gotti threw Sammy under the bus theory-
