Daniel Edward Rosen has broken major stories on the bureau, including Kash Patel's firing of members of an FBI counterespionage squad that specialized in Iran just days before the launch of Operation Epic Fury, and the FBI's decision to send rookie agents to conduct foot patrols with cops and other federal agencies — DHS and ICE among them — in Washington, D.C.

He also broke news on the impending resignation of podcaster-turned-Deputy Director Dan Bongino, the details of the bureau's controversial fast-track hiring program, Patel's abandoned plans to relocate the FBI National Academy from D.C. to Redstone Arsenal in Alabama, and Ghislaine Maxwell's unusual prison transfer deal with the Justice Department.

His writing has appeared in The New York Times, Esquire, New York magazine, the Santa Fe Reporter, and elsewhere. "The Deacon and The Dog," his 2022 retrospective of the infamous "Dog Day Afternoon" robbery, was named one of journalist Don Van Natta's favorites in The Sunday Long Read Newsletter and became one of the newsletter's most-read stories.

Rosen has worked as a breaking news, NYPD, courts, crime, and city politics reporter for the New York Observer, the New York Post, the New York Daily News, and Newsday, where he started his career. He has appeared on BBC Radio, NY1, City Cast DC, the Cold Red Podcast, the Original Gangsters Podcast, the Gangland Podcast, LI News 103.9, and Dan's Papers podcast.

He lives in Brooklyn with his wife and two children.
