Disclaimer: This is highly speculative but it might explain things.

Ah, yes, Executive Director of District of Columbia Public Housing, Brenda Donald, looked as if she had just had a good cry at a recent public event. I could not put my finger on it, as this was a celebratory event, I kept thinking why would she look so sad. This article MIGHT explain why she had been crying: most likely the Mayor let her know the article was coming out and she would need to resign.

Referenced event can be seen here. Note: You can literally see she had been crying.
