WASHINGTON: A document describing a foreign government's military defenses, including its nuclear capabilities, was found in the FBI's search last month of former President Donald Trump's Florida home, the Washington Post reported on Tuesday.

The Post report, which cited people familiar with the matter, did not identify the foreign government discussed in the document, nor did it indicate whether the foreign government was friendly or hostile to the United States.

Trump representatives and the Justice Department did not immediately respond to requests for comment from Reuters.

The FBI recovered more than 11,000 government documents and photographs during its Aug. 8 search at Trump's Mar-a-Lago estate, according to court records. 

According to the Post report, some of the seized documents detail top-secret U.S. operations that require special clearances, not just top-secret clearance.

Some of the documents are so restricted that even some of the Biden administration's senior-most national security officials were not authorized to review them, the Post.
