Five of Krieger and Cardinale's intended six witnesses were ruled irrelevant or extraneous, leaving only Gotti's tax attorney Murray Appleman to testify on his behalf. The defense also attempted unsuccessfully to have a mistrial declared based on Maloney's closing remarks. Gotti himself became increasingly hostile during the trial, and at one point, Glasser threatened to remove him from the courtroom. Among other outbursts, Gotti called Gravano a junkie while his attorneys sought to discuss his past steroid use, and equated the dismissal of a juror to the fixing of the 1919 World Series.
