Just been reading up on the author of that article, Kurt Eichenwald. Apart from an incorrect tweet about Trump's mental health history which he subsequently deleted, it would appear that his credentials as an investigative journalist are fairly good. That particular article does a hatchet job on Trump but if it had any significant inaccuracies, Trump would have sued and had it retracted as he has tried on numerous occasions. Eichanwald is also a recipient of an ethics in journalism award for what it's worth. I wouldn't be so quick to dismiss anything written by him; it's likely to be more accurate than anything you'll read on Breitbart or other Trump supporting websites.
