North Korea had just tested an intercontinental ballistic missile capable of hitting Alaska, and the Trump administration was scrambling to react. But it seems Nikki Haley, Trump’s ambassador to the United Nations, had lost her password for classified communications.

That’s why on that fraught July 4, 2017, she was typing away on her BlackBerry 10 smartphone, sending “confidential” information over a system meant only for unclassified material.

Haley was in a rush as she headed to her office—“On my way in”—shooting emails back and forth with top aides who’d been with her since she was governor of South Carolina. She needed to make a statement, and they were drafting it for her. “Let’s clean this up,” she writes after looking at some of the copy. “Pretty this up for me,” she says.
