"The Presidential Records Act requires all presidential and vice-presidential documents to be transferred to the National Archives once the official leaves office. Classified information is not permitted to be in private possession outside of strict rules and controls.

Unlike the case of former President Trump's documents, which is also under investigation, President Biden is not claiming to have had a right to possess the classified documents. In fact, he says he does not know their contents. Trump, on the other hand, had been actively negotiating with authorities, arguing he had a right to the documents, when the FBI raided his Mar-a-Lago home on August 8, confiscated and photographed the documents, then leaked information and photos to the press."
