• The FBI seized official White House documents from Donald Trump's Mar-a-Lago home on August 8.
  • Investigators left with 26 boxes of records, several of which were filled with classified documents, according to an NYT report.
  • More than 300 documents marked classified were recovered since Trump left office.

Federal investigators found batches of sensitive, official White House records in the basement of Mar-a-Lago and in the closet in Donald Trump's office, according to The New York Times.

The publication reported on Monday that Trump and his aides returned about 150 classified documents to the National Archives and Records Administration, even before the FBI raided the former president's Palm Beach, Florida home on August 8.

Over the course of the FBI search, Justice Department officials left with 26 boxes of documents, including 11 sets that were categorized as classified. One set of documents had top secret information, according to The Times.

It's not immediately clear how these documents are traditionally stored in the White House or how they would be stored in the National Archives, but several people familiar with the investigation told The Times that the FBI found documents in a container that was in a closet in Trump's office.

Another set of documents was in the storage area located in the basement of Mar-a-Lago.

Neither the DOJ nor representatives for Trump responded to Insider's request for comment.
