The subpoena is part of the formal process that FBI investigators and Justice Department prosecutors use to take possession of the boxes of documents from the Archives, which retrieved the boxes from the Florida resort.
A spokesperson for Trump said the former President “consistently handled all documents in accordance with applicable law and regulations. Belated attempts to second-guess that clear fact are politically motivated and misguided.”
The White House declined to comment.
The FBI routinely conducts reviews to determine if classified information has been stored in ways that don’t meet US government requirements and if any sensitive information has been exposed.
As part of that, the FBI will work with intelligence agencies that oversee the specific classified information at issue to determine how sensitive the documents are. The intrusive nature of the reviews likely means the FBI will have to examine where the documents were stored and who had access to them.
Most such reviews don’t result in criminal charges, but the probe is the latest example of Trump coming under scrutiny. His conduct after the 2020 election as well as his business practices are under investigation in Georgia and New York, and the House select committee investigating the January 6, 2021, attack on the US Capitol is looking at Trump’s role.
