© Jabin Botsford/The Washington Post Waltine “Walt” Nauta, aide to former president Donald Trump, disembarks Trump’s airplane in Bedminster, N.J., on Tuesday. A key question hovering over the case now is whether Nauta will cooperate with prosecutors against Trump in hopes of a lesser sentence. Trump and Nauta spoke repeatedly by phone before Nauta moved the boxes, the indictment alleges. “We’re going to start off by taking former president Trump first,” U.S. Magistrate Judge Jonathan Goodman said as he opened the session. After the court hearing ended Tuesday, Nauta joined Trump at a brief stop at Cafe Versailles, a Cuban restaurant in downtown Miami.
