The Obama administration has ruled that inspectors general have to get permission from the agency they're monitoring for access to wiretaps, grand jury and credit information, a decision that immediately was denounced by watchdogs and lawmakers. The Justice Department's inspector general said the 58-page ruling ... will undermine his ability to do his job rooting out fraud and corruption. "Without such access, our office's ability to conduct its work will be significantly impaired," Inspector General Michael E. Horowitz said in a statement. His disapproval was followed by a bipartisan condemnation from four congressional leaders whose committees have oversight over DOJ. [In] 2010 ... the FBI started restricting the DOJ inspector general's access to documents whose confidentiality is protected by law, including grand jury testimony and wiretaps. The IG's review of the controversial Fast and Furious case, the failed sting operation that lost track of more than 1,000 government-issued guns, one of which was used to kill a U.S. Border Patrol agent, was delayed. Other investigations have lagged, Horowitz testified before Congress last February, complaining that the FBI has failed to turn over key records in several whistleblower cases. "Imagine if we had a DOJ (inspector general) during Watergate looking at the FBI's conduct and the Attorney General had this opinion to deny or delay access to this kind of information," said Brian Miller, the former inspector general at the General Services Administration.
