The US National Archives had to reclaim former US President Donald Trump’s White House records, which involve his so-called "love letters" from North Korean leader Kim Jong Un.

The Washington Post reported today that he took them out when he left office by mistake, while usually, such documents and other items should be handed over to the agency.

The documents were recovered after discussions took place between the Archives and Trump’s lawyers that began last year, the newspaper added, and they included correspondence with Chairman Kim, dubbed "love letters" by Trump, as well as a letter left for him as successor by President Barack Obama.

While Trump advisers "denied any nefarious intent," the newspaper added that the retrieval of the boxes gives rise to questions about how much Trump adhered to the Presidential Records Act, which requires the preservation of memos, notes, letters, faxes, emails, and other written communications related to a president’s official duties.

In a 2018 interview with The Washington Post, Trump referred to his correspondence with Kim as "love letters," which according to him, prove their productive relationship. Despite meeting three times during his tenure in office, the negotiations between them failed to solve the nuclear crisis on the Korean Peninsula following a summit in Vietnam due to Washington's unwillingness to show a sign of goodwill by removing any sanctions in place.
