One almost wonders if this entire thing with the FBI raids wasn’t in fact an attempt by some apparatchiks to embarrass and humiliate Biden, maybe blackmail him and keep him in line? Whomever had copies of the diary had so far refused to publish them because it could not be verified. It wasn’t until the FBI went and raided people’s homes that the diary became widely known - and at least presumed to be authentic.
The diary has been widely discussed for over a year. There is nothing new here.
