Hanni Bleiweiss (Hebrew: חני בליוויס), also known as Hani Bliveis, served as Benjamin Netanyahu's personal secretary, close aide, and office manager (מנהלת לשכתו) for nearly 30 years, described as a powerful figure in the Prime Minister's office. She died of cancer in March 2023, after which Netanyahu publicly mourned her as a 'good friend' and loyal assistant. Controversies include a December 2024 Channel 12 'Uvda' investigation revealing WhatsApp correspondence where Sara Netanyahu directed Bleiweiss to orchestrate protests and online campaigns against Netanyahu's critics, including witness Hadas Klein in his corruption trial; the report portrayed Bleiweiss as loyal but allegedly mistreated by Sara while ill. Her family plans to sue the Netanyahu family and Likud for NIS 8 million (~$2.18M), alleging harassment, abuse, and humiliation that harmed her health, with police probes leading to phone seizures from her children.
