...print a follow-up press release about the further development of the situation and the charity's returning of the donation as a form of post-fact rejection? As has been previously mentioned, it is a press release, and a retraction (or in this case, correction) being printed is all that is needed to prevent them from making such cases.

Beyond that, you can not in any way be held responsible for a press release made by something that you have no control over. Baldur and Elminster are correct, the StC and State of Connecticut are very wrong, as have been stated.
