U.S. federal agents were looking for documents relating to nuclear weapons when they raided former President Donald Trump's home in Florida this week, the Washington Post reported on Thursday.
It was not clear if such documents were recovered at the former president's Mar-a-Lago resort in Palm Beach, the Post said. Reuters could not immediately confirm the report.
The U.S. Justice Department asked a judge on Thursday to make public the warrant that authorized the FBI search of Mar-a-Lago, after Trump, a Republican, portrayed it as political retribution.
The request means the public could soon learn more about what investigators were looking for during the unprecedented search of a former president's home.
The search was part of an investigation into whether Trump illegally removed records from the White House as he left office in January 2021, some of which the Justice Department believes are classified.
Attorney General Merrick Garland, the top law enforcement officer and an appointee of Democratic President Joe Biden, told a news conference that he had personally approved the search. The Justice Department also seeks to make public a redacted receipt of the items seized.
"The department does not take such a decision lightly. Where possible, it is standard practice to seek less intrusive means as an alternative to a search, and to narrowly scope any search that is undertaken," Garland said.
His decision to publicly confirm the search was highly unusual. U.S. law enforcement officials typically do not discuss ongoing investigations in order to protect people's rights. In this case, Trump himself announced the search in a Monday night statement.
Garland said the Justice Department made the request to make public the warrant "in light of the former president's public confirmation of the search, the surrounding circumstances and the substantial public interest in this matter."
A source familiar with the matter said the FBI retrieved about 10 boxes from Trump's property during the search.
Trump was not in Florida at the time of the search.
Late on Thursday, Trump called for the immediate release of documents related to the search.
"Not only will I not oppose the release of documents related to the unAmerican, unwarranted, and unnecessary raid and break-in of my home in Palm Beach, Florida, Mar-a-Lago, I am going a step further by ENCOURAGING the immediate release of those documents, even though they have been drawn up by radical left Democrats and possible future political opponents, who have a strong and powerful vested interest in attacking me, much as they have done for the last 6 years," he said on his Truth Social platform.
The government has until 3 p.m. (1900 GMT) on Friday to let the court know whether Trump's attorneys will object to unsealing the warrant. The case is before U.S. Magistrate Judge Bruce Reinhart, who reviewed the warrant to ensure the Justice Department had sufficient probable cause for the search.
While seeking to unseal the warrant, the Justice Department has not asked the judge to unseal the sworn statement in support of the warrant, the contents of which could potentially include classified information.
Two of Trump's attorneys, Evan Corcoran and John Rowley, did not respond to a request for comment.
In a statement earlier on his Truth social network, Trump said: "My attorneys and representatives were cooperating fully, and very good relationships had been established. The government could have had whatever they wanted, if we had it."
