Haberman's professional career began in 1996 when she was hired by the New York Post. In 1999, the Post assigned her to cover City Hall, where she became "hooked" on political reporting. Haberman worked for the Posts rival newspaper, the New York Daily News, for three and a half years in the early 2000s, where she continued to cover City Hall. Haberman returned to the Post to cover the 2008 U.S. presidential campaign and other political races. In 2010, Haberman was hired by Politico as a senior reporter. She became a political analyst for CNN in 2014. Haberman was hired by The New York Times in early 2015 to be a political correspondent for the 2016 U.S. presidential campaign. According to one commentator, Haberman "formed a potent journalistic tag team with Glenn Thrush". Her reporting style as a member of the White House staff of the Times features in the Liz Garbus documentary series The Fourth Estate. Among the daily frustrations of her work covering the Trump administration, she is also shown on camera in her role as a mother being interrupted during tense moments to take phone calls from her children, at one point declaring to her phone, "You can't die in your nightmares." In October 2016, one month before Donald Trump defeated Hillary Clinton in the U.S. presidential election, a document was released by WikiLeaks that showed the Clinton campaign's use of Haberman to place sympathetic stories in Politico. " has a very good relationship with Maggie Haberman of Politico over the last year. We have had her tee up stories for us before and have never been disappointed. While we should have a larger conversation in the near future about a broader strategy for reengaging the beat press that covers HRC, for this we think we can achieve our objective and do the most shaping by going to Maggie." In 2018, Haberman's reporting on the Trump administration earned the Pulitzer Prize for National Reporting, the individual Aldo Beckman Memorial Award from the White House Correspondents' Association, and the Front Page Award for Journalist of the Year from the Newswomen's Club of New York. Trump himself has repeatedly responded to negative articles in the Times by calling her a "Hillary flunky" and a "third rate reporter". In January of 2020, attorneys representing Nick Sandmann announced that Haberman was one of many media personalities that they were suing for defamation for her coverage of the 2019 Lincoln Memorial Confrontation
