Sexual harassment allegations[]

In 2021, multiple women anonymously accused Tillmann of various forms of sexual harassment. He issued statements of apology for behavior "fueled by a toxic mixture of alcohol, drugs, and cavalier sexuality", while denying one accuser's accusation of sexual assault.[1][2] Tillman's apology was followed by additional accusations, as well as multiple businesses severing ties with him.[3]
