What Donna Rachel Edmunds is not disclosing about this entire situation is that she offered to contribute to the report - but she also demanded to be paid for contributing and that doing it for free was apparently not an option.
So of course, she left - because she did not get paid. So it seems based on what we are seeing right now, her attack on the report was not JUST politically motivated.
But also her holding a grudge because she didn't get paid. So I find this reply particularly ironic and quite the projection - she tries so hard to keep attacking the person who posted the report, accusing him of everything she was caught allegedly doing herself.
It also goes to imply the type of character this Donna is, when instead of being fully concerned and committed to doing right by the victims, one of her main thoughts is "how am I going to make money from this?"
