Justice Department materials provided to the House Judiciary Committee have revealed new details about the federal investigation into former President Donald Trump's handling of classified documents after leaving office.

According to a January 13, 2023 briefing memo prepared for then-Attorney General Merrick Garland, federal prosecutors examined whether Trump showed a classified map to people aboard his plane, including Susie Wiles, who is now Trump's White House chief of staff. The incident occurred after Trump left office following his first term.

The documents also disclosed that among the classified records taken to Mar-a-Lago were materials of extraordinary sensitivity. One document had been distributed to only six people, while another set of classified materials was described as relevant to Trump's business interests.

The Justice Department materials were produced as part of the House Judiciary Committee's investigation into the federal probes of Trump. The briefing memo was prepared approximately six months before Special Counsel Jack Smith formally charged Trump with retaining classified documents at his Mar-a-Lago resort.

Separately, Senator Chuck Grassley released documents that critics allege show coordination between Smith's team and federal judges Beryl Howell and James Boasberg during the Trump investigations. The allegations have drawn criticism from conservative lawmakers and legal observers.

The document releases provide additional insight into the scope and timeline of the classified documents investigation that ultimately led to federal charges against Trump.
