The Washington Post reported Friday that Donald Trump took sensitive documents to his Mar-a-Lago resort in Florida and they might not be made public.
Some classified information was contained in 15 boxes of documents that Trump took to his Florida resort after he left office, according to National Archives officials.
Two sources told The Post that some of the documents were of the very highest levels of classification, and that they might not be able to be described in an unclassified way.
A source told The Post that only a few have clearances to review.
As a congressional committee ramps up its investigation into Trump's handling of White House records, the details emerge.
The contents of the recovered boxes were requested by the chairwoman of the House Oversight Committee.
The deadline to provide an inventory of the contents was set by the National Archives and Records Administration, The Post reported.
All presidential records that Trump had torn up, destroyed, mutilated, or attempted to tear up were requested by Maloney.
She asked for information about any reviews conducted by other federal agencies into the contents of the boxes.
In a letter to the National Archives on Friday, Maloney described Trump's handling of records as the largest-scale violations of the Presidential Records Act since it was enacted.
The Presidential Records Act requires presidents and White House staff to preserve official documents and communications, and turn them over to the Archives at the end of a president's term.
