That is the key exemption. What is a bona fide news interview? Can the host of an entertainment program conduct a bona fide news interview? That would be core to any legal case on this issue, if on were to take it that far.
The interpretation on this going back to the 80's when I had many cases of this when doing a news talk station in Puerto Rico is that a "news interview" is most closely associated with breaking news or spot news coverage, and not with a "think piece" in-depth sit-down interview.
Obviously, its not the 80's any more and the FCC is likely to have a different interpretation of what a "news interview" is but the concept remains to be tested in case law.
