Rep. John Dingell's investigation agenda as chair of the Commerce Committee if Democrats take the House:

Among the areas Dingell says he will investigate: "Privacy. Social Security number protection. Outsourcing protection. Unfair trade practices. Currency manipulation. Air quality.

"We'll look at the implementation of the Energy Policy Act of 2005. We'll take a look at climate change. We'll take a look at the nuclear waste programme, where literally billions of dollars are being dissipated. We'll look at port security and nuclear smuggling, where there's literally nothing being done. On health, we'll take a look at Medicaid. The Food and Drug Administration. Generic drug approval. Medical safety. We'll also take a look at food supplements, where people are being killed. We will look at the overall question of Katrina recovery efforts."

In a word: oversight.
