It is reported by Politico with reference to the warrant.
The search document examined by the publication indicates that the FBI is investigating Trump for a potential violation of the espionage law.
It is with this that the searches in his estate Mar-a-Lago are connected.
It is clarified that if Trump is brought under this law, this can lead to both a fine and imprisonment.
Earlier, Trump said that his Mar-a-Lago estate was searched by agents of the FBI.
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.
Trump also said that during the search, FBI agents asked everyone to leave the premises.
