O’Brien writes for Bloomberg View. “A decade ago, my lawyers questioned Trump under oath during a deposition in a libel case he filed against me for a biography I wrote, ‘TrumpNation.’ (Trump lost the case in 2011.) Trump had to acknowledge 30 times during that deposition that he had lied over the years about a wide range of issues.”
