Perhaps it's personal stuff that could be career-ending. The possibility of abortion was brought up. Anything that's potentially worse than cheating on your cancer-ridden wife could be pretty explosive.In that case it would be unethical to NOT release it. I have to assume it is just personal stuff for them to be conflicted, but maybe I am ascribing too high of a motive....
Also, you're making the assumption that the media actually has any sense of ethics. ABC will do whatever is in the best interest of ABC.
