Former President Donald Trump's staff moved boxes the day before a June 2022 visit to his Mar-a-Lago residence by the FBI and a federal prosecutor, a source familiar with the matter confirmed to CBS News. Trump's team was aware of the scheduled June 2022 visit, and held a so-called dress rehearsal for the visit ahead of time, the source told CBS News. The Washington Post first reported the movement of the documents. It's unclear exactly what the boxes contained.
