 Okay, I'm going to read one of the questions online, and then I'll turn to you. The question is, in the aftermath of Chevron deference, is Congress's power of the purse, its writing of appropriations laws, relevant to the court's interpretation of other laws? For example, should Congress's appropriations for the EPA affect the court's interpretation of the Clean Air Act? It's a hard one. Philip Wallach, American Enterprise Institute Senior Fellow.
