WASHINGTON -- The head of the Pentagon's investigative office, Jon T. Rymer, said Monday he is resigning, effective in January.
Rymer, who was confirmed by the Senate two years ago as the Pentagon's inspector general, said in a written statement that he plans to volunteer with a veterans' service organization before eventually returning to the financial services industry where he has worked for most of his career.
Rymer called his resignation a difficult decision but did not elaborate. He said his principal deputy, Glenn Fine, will take over.
Among other work, the inspector general's office is probing allegations by intelligence analysts at the U.S. Central Command that senior military officers there manipulated conclusions of intelligence reports on the war against the Islamic State to exaggerate progress. The inspector general also is investigating allegations of misconduct by Army Lt. Gen. Ron Lewis, who was abruptly fired Nov. 12 as senior military assistant to Defense Secretary Ash Carter.
"The work isn't easy but it is essential and I am proud to have been a part of it," Rymer said of his two years in the job.
Before taking the Pentagon post in September 2013, Rymer had served as inspector general at the Federal Deposit Insurance Corporation and at the Securities and Exchange Commission. He is an Army veteran.
