It wasn't too long ago that Woodward was all spun up over the "dirty dossier".
It may be that he has finally realized that what has been going down makes Watergate, the event that he built his career on, look like a game at a child's birthday party.
It may be that he knows that his glory has long since faded, and he doesn't want to miss out on this one.
And remember, if there is anyone who should know more than a great deal about highly classified gossip it is Woodward.
Woodward wants access to Trump so he can write a book. He’ll be more favorable than most of the MSM toward Trump. Keep an eye on what he says, IMO.
