Nothing blatantly interesting was said, so far as I can tell. But Joe did sound somewhat rehearsed and almost sounded like he wanted to talk through what he had rehearsed. Some details he knew quite quickly and clearly. Others he was somewhat fuzzy on such as when Seth Rich was shot. Somehow he knew he was at the White House four days earlier, but when it came to pinpointing when the shooting happened it was "Spring Break" or "sometime last year" or some such. My amateur opinion is that he's hiding something and even actively working to obfuscate the truth.
