Heather Ammel claimed in her suit that Ms. Sinema sent Mr. Ammel sexually suggestive photographs on Signal, the encrypted messaging app; chose him to accompany her on trips to Napa Valley and to the Sphere, an events venue, in Las Vegas; paid for him to enter psychedelic treatment for post-traumatic stress disorder and other issues; encouraged him to bring drugs on work trips so she could guide him through a psychedelic trip; showered him with gifts and concert tickets; and eventually entered into a sexual relationship with him that caused him to leave his family.
