Hans von Spakovsky details for the Daily Signal a recent complaint lodged by more than half of the federal government’s inspector generals.

In an unprecedented letter, a majority of the federal government’s inspectors general (IGs) claim that the Obama administration is obstructing their investigations into government mismanagement and corruption. So much for President Obama’s claim that his would be the most transparent administration in history.

And it truly IS unprecedented. Rep. Darrell Issa (R-Calif.), chairman of the House Oversight and Government Reform Committee, says “there has never been a letter even with a dozen IGs complaining” about such obstruction by an administration. The fact that the Justice Department’s IG, Michael Horowitz, also signed on is particularly revealing. After all, it is the duty of senior executive officers like Eric Holder to advise subordinate officials that they are obligated to cooperate with the IGs of their agencies.

On Aug. 5, 47 of the federal government’s 73 inspectors general, many of whom were appointed by President Obama, sent their letter to Issa, Sen. Thomas Carper (D-Del.), and the ranking members of the House Oversight and Government Reform and Senate Homeland Security and Governmental Affairs Committees — essentially pleading with Congress to help the IGs do their jobs uncovering waste, mismanagement, fraud, and corruption within their respective agencies.

In the letter, the IGs complain about the “serious limitations on access to records that have recently impeded the work” of IGs at the Peace Corps, the EPA, and the Department of Justice. Administration lawyers have construed laws related to privilege in “a manner that would override the express authorization contained in the IG Act” and seriously impede the “ability [of the IGs] to conduct our work thoroughly, independently, and in a timely manner.”
