Standing by his brother is one thing. Chris went far beyond that, using network sources and resources to cyber stalk the accusers. Sounds suspiciously close to witness intimidation.
I believe the proper journalistic ethics thing would have been for him to recuse himself from the story altogether. In retrospect should’ve done the same thing with the covid story, instead of inviting his brother to joke around on the air. Chris used his position of power to save a person who abused his position of power.
