Who Are The Anonymous Sources That Claimed That President Trump Insulted Dead US Soldiers?

WNU Editor: Some in the "right-wing" are speculating that it was Eric Ciaramella and [Lieutenant] Colonel Alexander Vindman who talked to Jeffrey Goldberg .... Former US Attorney Joe DiGenova on Last Week’s Atlantic Hit Piece: “My Guess is that Two of the Anonymous Sources are Eric Ciaramella and [Lieutenant] Colonel Alexander Vindman of Impeachment Fame” (Gateway Pundit). I am not sure about that. But I am willing to bet that the person(s) who talked to Goldberg were not even on the trip, and they were certainly not in the loop on President Trump's reasons for changing his travel arrangements. This sounds more like someone heard from someone else who had heard it from someone else and then peddled it to the Atlantic.
