He found it and reported it. Biden wasnt part of the equation. I can actually logically prove it too, as long as you are honest.
The guy called a department in the White House. I dont remember which one, but it was one of them. He didnt call Biden first because, if he had, he could have easily slipped those documents into his briefcase and hand delivered them to Biden, or burn them. That is assuming he is a shady lawyer.
It seems obvious that he is not a shady lawyer though. He probably didnt want to cover up a crime, so he did everything by the book to protect himself. He knows this is bad for Biden, yet he alerted the entire White House instead of keeping it quiet.
Does this seem logical and correct to you?
