I don’t think he knew at first but did later. So, what’s the point? He was deceived. I’m a doctor. People lie to me daily.
(1) in his position as CEO of Hardee's he should've known how to affirm citizenship of an employee and
(2) (very big deal) When he found out she was an invader, he should've demanded she be deported and help set her up in her homeland. Instead, he tried to get her legal status, by his own explanation. That's unacceptable. Why the heck would we want a Secretary of Labor who tried to get legal status for an invader he employed?
