evidence: I thought I’d seen the worst. After all, I served as chief of staff at the Department of Homeland Security for part of the Trump era. We believed the man’s immoral impulses could be managed. We were catastrophically wrong. I wrote an unsigned opinion piece from within the administration to shine a light on presidential misconduct, but it only got darker. So I quit my job, unmasked myself as the anonymous author, and recruited others to campaign against the president in 2020. Trump lost. In many ways, so did I. Contending with the vindictive chief executive nearly destroyed my life, from financial and legal troubles to stalkers and death threats. More importantly, it nearly destroyed our republic.
