If Swann is a friend, I question his judgement. Of all possible helpful things to investigate about all candidates he chooses this? Some help. The same way Hannity was "helping." According to him, he was doing it so that later on the democrats wouldn't bring it up.
Also, similar to Hannity, the excuse here is that we are looking at a different angle. "Byline." There are infinite different angles. "Management style" is another example. The last one pulled by Hannity: "I want to run the interview about newsletters, so that you can see that I treated Ron with respect." Aha. That's why you are running it the last hour before caucuses.
All these angles are excuses to keep this non-story in the news.
