She was being ironic - making fun of herself by pretending to be a ditzy, entitled white girl who though that she could never get AIDS. Unfortunately, in her absence, people took her literally and assumed she was serious.
She has plenty of reason to now explain it as being ironic, but we'll never know if that was her original intent, will we? Her other tweets from the same period strike me immature and mean-spirited.
My point is, it's natural for her to say afterwards that it was meant ironically now that the backlash has happened. Maybe she's just a jerk who got caught being a jerk.
She publicly broadcasted something that was, at best and assuming one gives her the benefit of the doubt, extremely insensitive and in any case indicative that she is perhaps not the best choice to be a communications director.
If an accountant got caught stealing in her off hours should she expect to find herself still employed?
