Hammered by White and her deputies, Trump ultimately had to admit 30 times that he had lied over the years about all sorts of stuff: how much of a big Manhattan real estate project he owned; the price of one of his golf club memberships; the size of the Trump Organization; his wealth; his speaking fees; how many condos he had sold; his debts, and whether he borrowed money from his family to avoid going personally bankrupt. He also lied during the deposition about his business dealings with career criminals.
Trump's poor performance stemmed in part from the fact that he was being interrogated by shrewd attorneys wielding his own business and financial records against him. But there were lots of other things that went wrong as well.
Trump is impatient and has never been an avid or dedicated reader. That’s OK if you’d rather play golf, but it’s not OK when you need to absorb abundant or complex details. Lawyers typically prepare binders full of documents for their clients to pore over prior to a deposition, hoping to steel them for an intense grilling. My lawyers did that prior to my own deposition in the Trump lawsuit. But Trump didn’t appear to be well prepared when we deposed him, a weakness that my lawyers exploited (and that Mueller surely would as well).
Trump, for example, had submitted a document to the court from his accountant outlining his assets and liabilities. He was proud of the document’s glowing conclusions but hadn’t seemed to have read most of it prior to sitting down with my lawyers – including a section that said that the report wasn’t a reliable gauge of his wealth. Trump seemed surprised when my lawyers pointed that out.
Trump also has a well-known inability to stick to the facts and a tendency to dissemble and improvise. While under oath, he’ll try to avoid saying that he’s lied in the past until he’s presented with documentation proving otherwise.
