Wolff even said in a recent interview, that there is nothing important in the book that was not already public knowledge. He also said everybody in the White House has their own press representative, and they spend all day talking to the press. So it's no wonder the place leaks like a sieve! Everybody has a different view of what's going on and what's important, so one way or another, there are no secrets. I think maybe quite a few of them are in "career saving" mode as well, so they want things released so later they look like they were not crooks. I bet they also all have lawyers!
