ABC News
Bruno joined ABC News in 1978 after leaving Newsweek. He oversaw ABC News' election and political coverage during the 1980s and 1990s. Ken Rudin, the current political editor of NPR who worked as Bruno's deputy at ABC News, described Bruno as "...the eyes and ears for Peter and 'World News Tonight' and Koppel." As political director, Bruno packaged much of the political headlines presented by ABC's best known reporters, including Ted Koppel, Cokie Roberts, Sam Donaldson, and Peter Jennings. Colleagues, such as Donaldson, have described Bruno as personally knowing nearly every major party county chairman in the United States. While much of his work at ABC took place off-screen, Bruno was invited onto news and talk shows owing to his political expertise. Bruno also hosted the weekly radio show, Hal Bruno's Washington, on ABC Radio until 1999. Bruno received public attention as the moderator of the 1992 vice presidential debate in Atlanta on October 13, 1992. The debate took place between incumbent RepublicanVice President Dan Quayle, Democrat Al Gore, and Independent retired Vice Admiral James B. Stockdale, who was the running mate of Ross Perot. The debate would become known for unusual responses and negative rhetoric from the candidates and the audience. It would later be called "the most combative debate in the 32-year history of the televised forums" by the Washington Post. One of the most memorable moments from the debate came early in the night. Bruno, in his capacity as debate moderator, asked James Stockdale, "Admiral Stockdale, your opening statement, please, sir?" Stockdale famously replied to Bruno's request: "Who am I? Why am I here?" Bruno also scolded the debate's audience when they jeered candidates Quayle and Gore, saying, "There’s no call for that ... so knock that off." He retired from ABC in 1999 to become the chairman of the National Fallen Firefighters Foundation.

Bruno originally became a volunteer firefighter during the 1940s and remained in firefighting for more than 60 years. He served as the chairman of the National Fallen Firefighters Foundation from 1999 to 2008 and remained Chairman Emeritus after retiring from the post.
