Bingo. She hired her through an employment agency. She paid her wages. She withheld all taxes including FICA. She had — from the employment agency — so-called proof the woman was a legal citizen complete with CA DL, green card, Social Security number, etc. Law in CA prohibited her from digging any deeper into the woman than that. I’m actually pretty darned impressed with Whitman over this, including that fact she paid the woman very, very well.
