Ex-US President Donald Trump has said his Florida home was raided by the FBI, and that agents broke open a safe.
Mr Trump said in a statement that Mar-a-Lago in Palm Beach was “occupied by a large group of FBI agents”.
Monday’s search was reportedly connected to an investigation into Mr Trump’s handling of official papers.
“These are dark times for our nation,” Mr Trump’s statement said. “Nothing like this has ever happened to a President of the United States before.”
“These are dark times for our nation,” Mr Trump’s statement said. “Nothing like this has ever happened to a President of the United States before.”
The FBI (Federal Bureau of Investigation) and the justice department have not commented on the reported search.
American presidents are required by the Presidential Records Act (PRA) to transfer all of their letters, work documents and emails to the National Archives (NA).
There are also other federal laws regarding the handling of classified documents.
Mr Trump’s lawyer, Christina Bobb, told NBC News that some papers had been seized during the search.
The dramatic escalation of law enforcement scrutiny of Mr Trump comes as the Republican prepares for a possible another presidential run in 2024.
Mr Trump said he had co-operated with all relevant government agencies and so the “unannounced raid on my home was not necessary or appropriate”.
He said it amounted to “prosecutorial misconduct” and “the weaponisation of the justice system” to prevent him from running for the White House again.
“Such an assault could only take place in broken, Third-World countries,” he said. “Sadly, America has now become one of those countries, corrupt at a level not seen before.
“They even broke into my safe!”
According to CBS News, the BBC’s US partner, Mr Trump was in Trump Tower in New York City at the time of the reported raid.
Eric Trump, the president’s second-oldest son, told Fox News that the FBI’s execution of the search warrant on Mr Trump’s Mar-a-Lago estate was related to an investigation into the handling of National Archives records.
In February, the NA – the agency that manages the preservation of presidential records – asked the justice department to investigate Mr Trump for his handling of official papers.
The NA said that earlier this year it had retrieved 15 boxes from Mar-a-Lago, some of which contained classified records.
NA officials say the former president illegally ripped up many documents. Some of them had to be taped back together, they said.
Mr Trump at the time rejected reports that he had mishandled official records as “fake news”.
A senior Trump adviser in Palm Beach told CBS the new search by federal agents on Mar-a-Lago was about the presidential records.
“This is about the PRA,” said the Trump source, who only agreed to speak on condition of anonymity.
“When have you ever heard about a raid because of PRA?”
The source added: “They [the FBI] just left and they left with very little.”
A federal search warrant must be signed by a judge. Though such a warrant does not suggest that criminal charges are expected, law enforcement agencies must first demonstrate they have probable evidence of illegality.
