Donald Trump improperly stored in his Florida estate sensitive documents on nuclear capabilities, repeatedly enlisted aides and lawyers to help him hide records demanded by investigators and cavalierly showed off a Pentagon “plan of attack” and classified map. That's according to a sweeping felony indictment that paints a damning portrait of Trump's treatment of national security information. The first federal case against a former president cuts to the heart of any president’s responsibility to safeguard the government’s most valuable secrets. Prosecutors say the documents he stowed, refused to return and in some cases showed to visitors risked jeopardizing not only relations with foreign nations but also the safety of troops and confidential sources.
