The Washington Post reported that Trump personally packed up 15 boxes of material.
The report states that Trump tried to get a lawyer to say that he had all the documents.
In the FBI raid on Mar-a-Lago, there were many secret and classified records.
The Washington Post reported that Donald Trump kept a lot of records back when he was president.
The paper reported that Trump ordered a lawyer to say that the documents had been returned. He refused to do it because he didn't know if it was true.
This was reported by the Post on the basis of anonymous sources.
A spokesman for Trump didn't reply to the Post's specific questions and didn't reply to Insider's request for comment.
The report that Trump chose the documents to be returned from Mar-a-Lago, while keeping some behind, could make his position worse in the legal case against him.
The process of packing up the boxes was kept out of the view of top aides.
According to documents released by the DOJ, the FBI seized top- secret documents from Trump's Mar-a-Lago residence.
He wanted to make a statement that all documents had been returned after he handed them over.
His lawyer refused to sign it. Cannon wasn't sure if there were any more documents at Mar-a-Lago.
A few months later another Trump lawyer, Christina Bobb, signed a statement saying that a search of Mar-a-Lago had found no more documents that needed to be returned.
The National Archives asked the Justice Department to investigate after they found at least 100 classified records in Trump's papers.
Those with high levels of classification were among the documents that were not returned in the previous handover.
A spokesman for Trump attacked the outlet instead of addressing the substance of the reporting.
The Post was the "partisan microphone of leakers and liars buried deep within the bowels of America's government," according to the spokesman.
Business Insider has an article on it.
