This bill requires the Department of Defense Inspector General to submit a detailed annual report to Congress documenting the department's efforts to investigate fraud, waste, and abuse in military spending. The report must include statistics on the number and dollar value of investigations completed and pending, how long investigations take, the resources spent on oversight, and recommendations for improving the investigation process. The legislation affects the Pentagon's oversight operations and the military departments' inspector general offices, as they will need to compile and report this data annually. The bill includes no specific funding authorization or timeline other than requiring annual submissions going forward. The reports must be made available to the public, increasing transparency around how the Defense Department identifies and addresses wasteful spending.
