(CNN)The National Archives acknowledged Friday it has discussed with the Department of Justice that classified records were found in boxes at Mar-a-Lago after former President Donald Trump left office, according to a letter from Archivist David Ferriero to the House Oversight Committee.
The letter, released by the Archives Friday, also provided more detail on reports that Trump tore up records after being warned not to while he was President. That letter is among four that the Archives released Friday portraying the agency, which acts as the historical library for the federal government, as concerned on multiple fronts about the Trump administration’s record-keeping practices.
The Archives arranged for the transport of about 15 boxes of records from Trump’s Florida resort last month after the agency sought them from the former President’s team.
“NARA has identified items marked as classified national security information within the boxes,” Ferriero wrote, responding to a question from the House. “Because NARA identified classified information in the boxes, NARA staff has been in communication with the Department of Justice.”
The Justice Department did not immediately respond to a request for comment. CNN previously reported that the Archives had asked the Justice Department to investigate Trump’s handling of White House records.
The Archives said in the Friday letter that it is “in the process of inventorying the contents of the boxes.” That process is expected to be complete by February 25, Ferriero wrote.
Social media records
The Archives also said in letters to Congress Friday that some social media records and messaging on apps used by White House staff weren’t properly kept as official documents despite previous warnings to Trump officials.
Among the missing records mentioned are those associated with Trump’s personal Twitter account, including deleted tweets. Ferriero wrote that the Archives had previously raised concerns that Trump’s deleted tweets were not being captured and was “informed by White House officials that they [were], in fact, doing so.”
