Leiberman has been a reporter for
WBFF in
Baltimore and the newsman at
WIYY 98 Rock radio in Baltimore. He has also worked as a reporter in
New Mexico and
Kansas. In October 2004, Leiberman made headlines when he was fired by
Sinclair Broadcast Group for publicly questioning the company's decision to air
Stolen Honor: Wounds That Never Heal, a 40-minute film critical of Presidential candidate
John Kerry's role in the anti-war movement during the
Vietnam War. Leiberman claimed he was fired by Sinclair for criticizing the film in
The Baltimore Sun as "biased political propaganda," and later told CNN: "The reason for my firing was that I relayed what they called proprietary information from an in-house meeting and I divulged it to the media, which is against company policy." In 2006, Leiberman began reporting for ''
America's Most Wanted'', the long-running
reality TV series hosted by
John Walsh that profiles cases of wanted criminals. He reported mostly on cases from
New York, such as
Ralph "Bucky" Phillips, but he has also reported on the cases of Jose Campean,
Ignacio Ramos and Gilmer Hernandez. In August 2011, he joined
Sirius XM Radio as a reporter for
The Howard Stern Show and Stern's
Howard 100 News department, replacing investigative reporter Steve Langford. In January 2013, Leiberman began to host
Leiberman Live, a news radio show airing on
Howard 101. He is also currently the host of
TrueFacts with Jon Leiberman on cyberstationusa.com, as well as a regular contributor to
HLN on crime issues. Leiberman's book written with author Margaret McLean on
Whitey Bulger,
Whitey on Trial: Secrets, Corruption, and the Search for Truth, was released by
Forge Books in February 2014. In December 2024, Leiberman joined Qwoted, a media relations network, as the Global Head of Media, a newly-created position. His role was to strategically attract and retain media members. He left the position in June 2025. ==Personal life==
