Jim's comparisons and examples are always good for a laugh. Aside from a huge difference in credibility, which Woodward has in abundance, and which Judith Miller doesn't have any, her jail time resulted in her refusal to reveal a source in a case that directly involved an ongoing national security issue under investigation. She waded in with inaccurate information that disrupted the investigation, which is why she got arrested for not revealing the source, and it turned out her source had a political motivation for using her that way. She served prison time because of it. The NYT dumped her because of her inaccuracies in reporting on the Iraq war, during which she made up information about Iraq's nuclear capabilities and WMD development, which Bush administration officials cited as if it were accurate. She then cited the Bush administration's quotes as proof for her story. The Times doesn't put up with that kind of exaggeration and lying, so they fired her, and she went to work for Fox News. A good reporter knows the difference between protecting a source, and getting caught up in the middle of an ongoing investigation to try and change or fix the outcome.
I've watched a couple of Woodward's interviews. He's a class act. He reacts to facts, so if his accuracy is questioned, and there's factual information to support a different perspective, he'll acknowledge he made a mistake. Those incidents are rare, though, because he is so thorough. And all of the information in this book is about the conduct and activity going on in the White House. Nothing about national security is being revealed. His book just corroborates what many of Trump's White House staff have already said goes on.
