I think there is little to some truth in there. But like most or all anonymous sourced books/articles most of it is highly exaggerated. If you want to believe some of what is in his book then he accidentally (or purposely) debunks the MSM’s Russian collusion hoax. Also, it is too much of a coincidence that the NYT op-ed comes out a day after and says almost word for word some of the the same things. So it sounds like it might be just one person trying to make extra money by leaking info and lies. Either way, there are always two sides to everything and a person who only wants to believe one side of anonymous sourced and written things without hearing the other side is a fool. Especially when most of the book and op-ed articles have been debunked already and reliable sources claim that some of these anonymous sourced items are lies.
So do I want to believe anonymous sources about anything? I think I am smarter than to fall for such diatribe. JMHO
The op-ed saying a lot of the same things could be seen as indications of dishonesty, but it could also be indications of corroboration. Hard to know if they had anything to do with each other. Woodward might have been using the author of the op-ed as one of his sources which would explain the similarities either way.
I do know that being anonymous doesn't inherently discount what is being reported. There are many valid reasons for someone wanting to remain anonymous.
I haven't seen proof that what the book claims are lies. Only contradictory evidence I see are Trump's staff saying that they never said those things. Of course it could be because those things are lies, but it could also be because they don't want to admit saying bad things about Trump.
To me, one of the things that lends credibility to the anonymous source's claims is that the behavior alleged by Trump seems rather consistent with stuff he already says publicly. Of course it could be a well manufactured lie, but many of the things being reported in the book aren't exactly a surprise given what he tweets and says in public.
