Saw this in F.Loc's Wikipedia.

Apparently, after finding out that Gravano in his book Underboss claimed that after the infamous oranges jail episode, FL & SG agreed that if they were found not guilty, they would both kill Gotti, at a victory party for beating the case.

" But I got to bring him ( JG) there and be the shooter " Sammy claims FL said..

And JG reaction:
"According to law enforcement sources and court papers, an infuriated Gotti, who was serving a life sentence in Marion, Illinois, reached out to the Aryan Brotherhood prison gang to kill LoCascio. Sources said they believe that two members of the white supremacist group were used"

Find this hard to believe, Gotti must of known that Gravano was shit stirring.
Don't even believe the oranges story. Can imagine something like it happened but not ending with Gotti driving FL to tears.

Then again Sammy also wrote that it was his b-i-l Eddie who made him rat.
