Donald Trump’s lawyers on Thursday ripped the former president’s accountant for claiming “I don’t know” or “I don’t remember” dozens of times during his testimony at trial in the New York attorney general’s $250 million civil fraudcase.

Donald Bender, a partner at accounting firm Mazars USA, had been under tense cross-examination by Trump’s attorneys since Tuesday afternoon when they called him out over his apparent memory loss during the final hours on the witness stand.
