[5] In 1990, Rosenberg was hired as a foreign correspondent by the Miami Herald; she covered many international stories for them, including in war zones.

At the time, Clarence Page wrote that at one point, Rosenberg and Susan Sachs of Newsday were barred by Pentagon officials from reporting on the 1st Marine Division's activity during the 1991 Gulf War.

[5] In addition to her written journalism, Rosenberg has spoken about Guantanamo, the government's constraints on the press at the facility, and related issues of reporting on PBS's NewsHour and CBC Radio's international news program Dispatches.

[9] In The Least Worst Place, Karen Greenberg described Rosenberg regularly scanning the bases' flagpoles, as new flags could mark the arrival of new military units; she also asked about them at briefings to keep up to date on the Americans stationed there.

[10] Following the official report that three captives had committed suicide on June 10, 2006, camp authorities ordered Rosenberg and three other journalists there to leave the facility, temporarily causing a news blackout.

[11] Rosenberg and Carol J. Williams of the Los Angeles Times had arrived early to prepare for a June 12 tribunal hearing.

[13] On June 18, 2013, Rosenberg republished a list of the dispositions of the Guantanamo captives, which was sent to her in response to a Freedom of Information Act request.

On January 8, 2019, Rosenberg broke a story describing how partially redacted transcripts from a pre-trial hearing of Guantanamo Military Commission of Khalid Sheikh Mohammed, seemed to indicate that Director of the Central Intelligence Agency, Gina Haspel, had been the "Chief of Base" of a clandestine CIA detention site in Guantanamo, in the 2003-2004 period.

[17][18][19][20] When the complaint first broke, Carol Williams, a reporter at the Los Angeles Times and friend of Rosenberg, dismissed Gordon's letter, saying, "This is an attempt to discredit a journalist who has managed to transcend incredible odds to cover a story of tremendous significance to the American public."

[21] After interviewing both reporters and other Guantanamo staff who would have been present during the incidents, the internal inquiry "did not find corroboration" for Gordon's claims.

[22] Elissa Vanaver, the Miami Herald's Vice President of Human Resources, wrote to the Pentagon to inform the authorities of the paper's conclusions reached by their inquiry.

On February 5, 2019, The Washington Post's media critic, Eric Wemple, reported McClatchy, the Miami Herald's parent company, had announced that conditions within the news industry would force it to offer early retirement to senior staff, including Rosenberg.

[27] Wemple quoted former Miami Herald managing editor, Mark Seibel: Wemple quoted Charlie Savage, of The New York Times:[27] In its reporting, the Miami New Times pointed out that McClatchy's CEO Craig Forman received a bonus of $900,000 on top of his base salary of $823,846 and $552,684 in stock awards, in 2017, writing "while the news is soul-numbing for reporters, life is still apparently pretty good for Forman and the rest of the newspaper chain's corporate board.
