From an AP story by Chris Megerian headlined “In Washington, ‘classified’ is synonymous with ‘controversy'”:

Hillary Clinton’s presidential dreams were undermined by her use of a private email server that included classified information.

Donald Trump has risked criminal charges by refusing to return top-secret records to the government after leaving the White House.

And now misplaced files with classified markings has led to another investigation that’s causing a political and legal headache for President Joe Biden.

The three situations are far from equivalent. But taken together, they represent a remarkable stretch in which document management has been a recurring source of controversy at the highest levels of American politics.
