When the FBI raided the offices of California State Sen. Ronald Calderon in June 2012, the state's news media had little idea of what was really going on. Some reporters immediately speculated that the raid was related to links Calderon had with a Southern California water district. But they were wrong. Indeed, no one knew the extraordinary story behind that FBI raid until Al Jazeera's Investigative Unit obtained, through confidential sources, a 124-page sealed affidavit that laid out the government's case against the embattled senator. In its series, titled “Hollywood Sting,'' Al Jazeera's Investigative Unit exposed the sordid tale of Sen. Calderon's alleged bribery and corruption and brought viewers and readers inside the unfolding narrative of an elaborate FBI sting. The network devoted more than an hour of on-air coverage to the story and published its findings on Oct. 30, 2013. The story prompted a “leak'' investigation by the U.S. Justice Department into how Al Jazeera's Investigative Unit obtained the secret affidavit. DOJ announced the inquiry the day after we broke the story. Just last week, a special agent for DOJ's Office of Inspector General contacted James Wedick, a former senior FBI supervisor who was interviewed for the story. The investigator sought to question Wedick about Al Jazeera correspondent Josh Bernstein's contacts in the bureau. The investigator also contacted a lawyer representing Al Jazeera.
