Vince Gray‘s lame duck administration is losing another cabinet-level official. According to a press release from the mayor’s office, D.C. Inspector General Charles Willoughby told Gray recently that he’s retiring.

In the release, Gray thanked Willoughby for his nine years of service since being appointed acting IG during Anthony Williams‘ administration in 2005. It’s good that Gray is finding nice things to say about Willoughby, because LL is having trouble doing the same.

Over the past few years, Willoughby’s distinguished himself by being uninterested in doing much investigating. In 2011, Willoughby opted against investigating Gray campaign whistleblower Sulaimon Brown‘s allegations on a pretext. His office went on to produce incurious looks at both Ward 1 D.C. Councilmember Jim Graham‘s Metro dealings and the D.C. Public Schools test erasures scandal.

Instead, Willoughby’s office spent its energy pursuing handicap-parking placard scofflaws. And who could forget Willoughby’s feud with the Board of Ethics and Government Accountability, the rare District government watchdog that actually turns out worthwhile investigations?

Willoughby didn’t respond to an immediate request for comment about his future plans.
