The leak of hundreds of classified intelligence documents about the war in Ukraine and U.S. spying on allies has left many officials asking: How did this happen again? That makes no sense,” said one former senior intelligence official familiar with past leaks, who, like others, spoke on the condition of anonymity to discuss sensitive matters. “The irony was we had gotten rid of thumb drives in 95 percent of [NSA] computers,” said the first former intelligence official. The New York Times first reported on April 6 that classified documents had shown up on other Discord servers and on social media platforms. On Wednesday, Discord provided authorities with the user information for the account that originally shared the classified information.
