Israel-American billionaire Arnon Milchan lambasted Israeli right-wing attacks on his aide Hadas Klein, a key witness in the trial of Benjamin Netanyahu who filed a police complaint on Thursday against a journalist for harassment.

Klein has this week been giving testimony in Case 1000, in which Netanyahu is charged with fraud and breach of trust for allegedly accepting luxury gifts from Milchan and Packer worth NIS 691,776 ($200,000).
