Correction:
He wasn't fired for helping his brother.
He was fired for how he helped his brother, abusing his position at CNN in order to further that goal.

The twitter blurb gets it right: "exactly how". The technical details matter.

With political correctness these days, maybe CNN would judge some abuses differently than others, so it's possible that his helping his brother is important. But on the other hand, the core issue is still that he abused his position at CNN.

I mention this before people go off on a hot take "of course I'd stand by brother even if he was accused of heinous crimes". I certainly would -- within the bounds of ethics, though.

CNN isn't forthcoming on details, but among the things was using his various contacts to discover what other reporters were going to say and influence them. This would hurt CNN's reputation.
