Beyond Hersh's unnamed source, not that I know of. Again I don't believe it disbelieve it. But I don't dismiss it out of hand because it's not enumerated in an NYT article or a wikipedia page.
1. Stoltenberg didn't get arrested because he was the son of a high-ranking government official.
2. He had a secret history of collaboration with American intelligence going back to his teenage days that is only being mentioned now in a single line in a paragraph with several other factual inaccuracies.
Good points, perhaps he was connected with American intelligence at such an early because his father's positions in defense and foreign affairs. Seems even more plausible.
