Donald Trump and the Justice Department are at odds over the first set of documents that will be reviewed by a special master.
The DOJ sent a letter to Judge Raymond J. Dearie, who has been tasked with overseeing a review of the more than 13,000 documents seized by the FBI during a raid at Trump's Mar-a-Lago residence.
According to the letter, Trump claims that nine of the 15 documents are his personal property and should be returned to him. The official documents from the White House should be deposited to the National Archives, according to the government.
The DOJ is investigating whether Trump mishandled White House records after he left office.
The DOJ letter states that the records include "supporting materials and relate to the president's power to grant reprieves and pardons for offenses against the law."
It was not known who made the requests.
Two documents related to his administration's immigration policies, as well as an email he received while in office from someone at a military academy, were disputed by Trump.
All materials created or obtained while a president is in office are classified as government property and destined for the National Archives at the end of his term, according to the Justice Department.
The FBI did not take Trump's personal records during the court-approved search, according to federal lawyers.
Criminal investigations seize personal records that are not government property. The letter said that the commingling of more than 100 documents with unclassified and personal records is important evidence in the government's investigation.
The Supreme Court's rejection of Trump's request to intervene in the dispute dealt a blow to the former president's attempts to slow the investigation.
