Zeev Rubinstein was close to Netanyahu and now lives in the United States. During his investigation abroad by the Israel Police, he gave up in the middle, and will now be called to testify in Israel as part of case 4000.

Rubinstein will present testimony, the main part of which is the presentation of his correspondence in front of the witness Ilan Yeshua. In the 2000 case, the court approved the submission of a re-production of the Netanyahu-Moses tapes.
