The Wall Street Journal writes about this, citing an inventory of items.
It is noted that some documents are marked as top secret and access to them is provided only in special government agencies.
The FBI also removed from the estate about 20 boxes containing various items, materials, photographs and handwritten notes.
Politico previously reported that the FBI was investigating Trump for potential violations of the espionage law.
It is with this that the searches in his estate Mar-a-Lago are connected.
Before that, Trump said that FBI agents searched his Mar-a-Lago estate.
According to the former US president, the search, which he called an attack by "radical left-wing Democrats", is related to their desire to prevent him from running in the 2024 presidential election.
