Israel's attorney general has ordered an investigation into Prime Minister Benjamin Netanyahu's wife, Sara Netanyahu, on suspicion of harassing political opponents and witnesses in the leader's corruption trial. The investigation comes after a report by the 'Uvda' investigative program uncovered WhatsApp messages in which Mrs. Netanyahu appears to instruct a former aide to organize protests against political opponents and intimidate a key witness. The announcement did not mention Mrs. Netanyahu by name, and the Justice Ministry declined further comment. This is the latest legal trouble for the Netanyahus, who are already facing corruption charges.
