Trump was issued subpoena for folder marked ‘Classified Evening Briefing’ discovered at Mar-a-Lago

Exclusive: Subpoena was issued last month after the folder was observed in Trump’s private quarters at the property

Donald Trump’s lawyers turned over an empty manilla folder marked “Classified Evening Briefing” after the US justice department issued a subpoena for its surrender once prosecutors became aware that it was located inside the residential area of the former president’s Mar-a-Lago resort, two sources familiar with the matter said.

The previously unreported subpoena was issued last month, the sources said, as the recently appointed special counsel escalates the inquiry into Trump’s possible unauthorized retention of national security materials and obstruction of justice.
