Rosen has reported from three-dozen countries across five continents, including Iraq, Afghanistan, Pakistan, Israel, the Palestinian Authority and numerous countries in Africa.

In 2006, Rosen was the first U.S. journalist to confirm that North Korea had conducted a nuclear test and anchored FOX News’ overnight coverage of the death of former President Gerald R. Ford. Prior to his current beat, he served as a White House correspondent, covering the last year of the Clinton presidency and the entire first term of George W. Bush.

Rosen has also secured numerous exclusives for FNC, including sit-down interviews with four justices of the U.S. Supreme Court. In July 2003, Rosen conducted an exclusive interview with Supreme Court Justice Sandra Day O’Connor, in which the justice discussed, for the first time, the Court’s workings during the historic "Bush v. Gore" case. In May 2001, Rosen conducted an exclusive interview with Chief Justice William H. Rehnquist. This was Justice Rehnquist’s first interview with a television news organization, and the first time news cameras were permitted inside the chambers of any Supreme Court justice. Earlier, Rosen secured a rare interview with five-time Pulitzer Prize-winning editorial cartoonist, “Herblock,” conducted in the Washington Post studio where the artist drew his daily cartoon from 1946 until his death in 2001.
