Don't let them off the hook yet. According to this article they didn't fire her. She quit after they "tried to keep her quiet about attacking LGBTQ books in libraries."
If Nestle hasn't publicly distanced themselves from her, they're probably still willing to employ her. I wouldn't be surprised if they were secretly donating to her campaign.
I guarantee she was a vocal bigot and only got in trouble with Nestle once it because clear she was a PR disaster. Bigots like this can't control themselves and definitely have red flags.
