Shaked told Israel's Channel 2 on Saturday that ministers have to resign in such cases, but not necessarily prime ministers.
Netanyahu, 67, is a suspect in two cases.
Israeli police suspect Netanyahu, prime minister since 2009, of being involved in bribery, fraud and breach of trust in two cases.
They rejected Regev and Edelson's claims regarding the violation of their privacy and stated that "the public interest in disclosing the requested information exceeds، in the circumstances، the right of Adelson، Regev، and the Prime Minister to privacy".
Harow, Netanyahu's chief of staff from 2014 to 2015, had been under investigation for allegations that he used political connections to advance his business interests. One, dubbed by the police as "Case 2000", involves secret talks he held with the owner of a large Israeli newspaper called Yediot Aharono about reducing the competition in the news sector in return for more positive coverage.
Adelson, a casino magnate, and his wife during recent visits to Israel have been questioned twice by police investigators in corruption scandals that allegedly involve Netanyahu.
According to legal analysts in Israel, it is likely Netanyahu will face charges, potentially forcing him to end his fourth term as prime minister years before scheduled elections.
Harow was Netanyahu's chief of staff in 2008 when he was opposition leader.
Netanyahu has repeatedly denied wrongdoing. "We can not go without a "weekly affair", so I want to tell you, citizens of Israel, I'm not referring to the background noise, I'm continuing to work for you", Netanyahu said in a video published on his Facebook page last Friday. If indicted, however, the prime minister would not have to immediately leave office, but rather only if he is convicted of a crime carrying moral turpitude.
Netanyahu must transfer the call log to Channel 10 and Drucker within 15 days. His passions include: gooey chocolate chips, black coffee, mountains, the Animal Kingdom in general, and John Lennon.
