Michael Hastings, the journalist whose reporting brought down the career of General Stanley McChrystal, has died in a car accident in Los Angeles, California. He was 33.

His legacy of reporting includes an exposé of America’s drone war, an exclusive interview with WikiLeaks founder Julian Assange at his hideout in the English countryside, an investigation into the Army’s illicit use of “psychological operations” to influence sitting Senators and a profile of Taliban captive Bowe Bergdahl, “America’s Last Prisoner of War.”

In addition to his work as a contributing editor for Rolling Stone, Hastings also reported for BuzzFeed. He leaves behind his wife, the writer Elise Jordan.
