Earlier quoted context omitted.
There is nothing illegal (or even unethical in my opinion) to give someone an article before publishing so they can comment on it. It's ridiculous to infer collusion when the result is such a negative article about Clinton. Which piece of information did not make it into the article because it was first send to Paustenbach? Please be specific.
I didn't say it was illegal. I do think it is unethical. It's what we call in legal world an ex parte communication. It's an off-the-record communication with the subject of the article. At the very least, it gives the subject advance warning to spin or do damage control in response--a courtesy I suspect is not granted to everyone.
It is standard practice in every bit of journalism I've ever seen to ask the subject for comment.
