Overview

  • Madison Busby, a former Halter Ranch employee, alleges Wyss groped her, exposed himself, and propositioned her and her husband for group sex over several years.
  • Busby claims Wyss retaliated after she rejected his advances, including raising her rent, cutting her pay, and ultimately forcing her resignation in July 2024.
  • The lawsuit, filed on April 21, 2025, in San Luis Obispo County, accuses Wyss of sexual battery, harassment, and retaliation, citing a 2022 admission where he reportedly said she would win if she sued.
  • Halter Ranch has publicly denied the allegations, stating it will present evidence to counter the claims, while Wyss has not issued a personal statement.
  • Wyss, a prominent Democratic donor, has faced similar allegations in the past, settling a 2013 harassment lawsuit for $1.5 million, raising questions about accountability within his philanthropic networks.
