The Washington Post reported that a Trump worker testified to federal agents that Donald Trump ordered employees to move boxes of White House documents to his home at the Mar-a-Lago resort.
The testimony sheds light on Trump's actions before the FBI raided the former president's resort home.
The Justice Department subpoenaed additional sensitive documents that may still be in Trump's possession before the FBI searched his house. The National Archives of Records and Administration found classified documents in a set of 15 boxes Trump's team gave them.
The records agency referred the matter to the justice department.
Thousands of official documents were found in the FBI search in August. Material was found in various locations of the Mar-a-Lago property, including a closet in Trump's office and a storage area in the basement.
The witnesses account of Trump's request was supported by security footage that showed people moving the boxes, according to anonymous sources. The witness is a key part of the investigation.
The witness initially denied handling the documents in a first interview with the FBI, but then changed the story in a second interview as the Justice Department gathered more evidence.
A request for comment was not responded to by a Trump spokesman.
Taylor Budowich, a spokesman for the Biden administration, said in a statement to The Post that the administration has weaponized law enforcement. The President has ultimate authority to categorize records, and what materials should be classified, and every other President has been given time and attention to this.
Budowich accused the Justice Department of leaking "misleading and false information to partisan allies in the fake news" in his statement to The Post.
Some of the records retrieved from Mar-a-Lago were so sensitive that some senior national security officials don't know about them.
