Trump employee tells FBI that Trump directed boxes to be moved at Mar-a-Lago after subpoena served

CNN) - A Trump employee has told the FBI about being directed by the former President to move boxes out of a basement storage room to his residence at Mar-a-Lago after Donald Trump's legal team received a subpoena for any classified documents at the Florida estate, according to a source familiar with the witness' description. The FBI also has surveillance footage showing a staffer moving boxes out of the storage room, the source told CNN. The witness account of Trump's actions after the subpoena was served in May coupled with the footage could be key to the federal criminal investigation that's looking into a range of potential crimes, including obstruction, destruction of government records and mishandling of classified information. FBI agents executed a search warrant at Mar-a-Lago in August and seized thousands of documents, including about 100 marked as classified. The FBI also subpoenaed the Trump Organization for surveillance video from the resort. The Trump employee initially denied handling sensitive documents or boxes at Mar-a-Lago, according to the source. But the FBI developed evidence that prompted investigators to go back to the witness, who revised their story to say Trump had given instructions to move the boxes, the source said. The Washington Post was the first to report on the witness account.
