Why it matters: The National Archives isn’t the only federal agency facing a deluge of threats. The FBI and Department of Homeland Security have also seen a surge in threats to law enforcement in the wake of the Mar-a-Lago investigation. What they say: “NARA has received messages from the public accusing us of corruption and conspiracy against the former President, or congratulating NARA for ‘taking him down,’” archivist Debra Steidel Wall wrote in an email to staff Wednesday. the Washington Post reported.

“Neither is accurate or welcome,” Steidel Wall wrote of the two types of messages.

The big picture: The National Archives has been embroiled in a protracted battle to recover documents from the Trump administration.

After the agency recovered 15 boxes from Mar-a-Lago in January, it later confirmed it found classified information among the documents. National Archives officials believed more materials were still missing and referred the matter to the Justice Department, according to the Washington Post. The FBI’s investigation into Mar-a-Lago earlier this month led to the removal of 11 sets of classified information from Mar-a-Lago, including “Miscellaneous Secret Documents/TS/SCI” — referring to documents containing “top secret ” or ” sensitive partition information.”
