Donald Trump appeared in Florida on Monday for a closed-door hearing to discuss classified discovery that the former president may want to use to defend himself in the case against him related to allegations he illegally retained national defense information after he left the White House.

Trump, according to a campaign spokesman, attended the hearing at the federal courthouse in Fort Pierce, where he was set to meet in person with Judge Aileen Cannon, who is overseeing the case, for the first time.
