Regarding the May 6 Center for Public Integrity news article “Pentagon: Whistleblowers left vulnerable”:

It is important to understand that the “internal Pentagon report”referred to in the article was, in fact, a review that I initiated on Nov. 1, 2010, as the principal deputy inspector general for the Defense Department. The review was conducted by our inspector general staff. The article may have led readers to believe that this review had been initiated and conducted by an entity outside the inspector general’s office.

Furthermore, in the April 24 letter from Sen. Charles E. Grassley (R-Iowa) mentioned in the article, Mr. Grassley referred to the internal review “as an excellent, hard-hitting example of self-examination. It may be the best [Office of Inspector General] internal review I have ever seen. Those responsible for producing it deserve praise and encouragement for their professionalism, courage, and dedication to the IG’s core mission.”

The increased hiring of staff in support of reprisal investigations and the changes to practice subsequently initiated were based on my review of the internal report.

I am committed to continuing on a path to establish a model whistleblower program for the Defense Department.
