Alexi McCammond, who made her name as a politics reporter at the Washington news site Axios, had planned to start as the editor in chief of Teen Vogue next Wednesday.
Now, after Teen Vogue staff members publicly condemned racist and homophobic tweets Ms. McCammond had posted a decade ago, she has resigned from the job.
Condé Nast, Teen Vogue’s publisher, announced the abrupt turn on Thursday in an internal email that was sent amid pressure from the publication’s staff, readers and at least two advertisers, just two weeks after the company had appointed her to the position.
