I learned tonight from a reliable source on Capitol Hill that the Inspector General of the Department of Labor has agreed to probe the sweetheart deal the agency struck with Wal-Mart that let the company get away with a puny $135,000 and change fine and a promise the DOL would give Wal-Mart a 15-day heads-up before launching investigations in the future.

As I wrote in my TomPaine column, this has got to be a wake-up call for corporate crime against workers.

I’ll post the details of the IG’s letter to Rep. George Miller after its release Friday (tomorrow).
