Donald Trump answered questions for seven hours on Thursday during a deposition called by New York Attorney General Letitia James.
The former president was deposed for a second time as part of a $250 million fraud case in which he is accused of falsifying the value of his properties and which seeks to ban him from doing business in New York State.
Trump's lawyer said he was 'eager to testify' to clear his name of those allegations and that he has 'nothing to conceal'.
Trump was pictured leaving Trump Tower in Manhattan at around 9.30am before traveling by motorcade to the attorney general's office, where prosecutors grilled him throughout the day.
His cooperation marks a departure from his approach during the first deposition last August in which he pled the Fifth Amendment 400 times and said he would be an 'absolute fool' not to.
