Congressional investigators have not produced evidence to link the harassment of conservative groups to the White House or to higher-ups in the Obama administration. But the lack of evidence that any political appointee was involved hasn’t stopped the lawmakers from assuming that it simply must be true. And so, they are going to hold hearings until they confirm their conclusions.

Monday afternoon’s IRS hearing was held by the Appropriations Committee. Judging from the less-than-capacity crowd, public enthusiasm for the inquiries is waning. But for those who missed that hearing, another was scheduled for Tuesday morning so the Ways and Means Committee could take shots at the agency. On Thursday, Issa’s committee will meet yet again to discuss the topic.

The lawmaker holding the gavel at Monday’s hearing, Rep. Ander Crenshaw (R-Fla.), chairman of the Appropriations subcommittee on financial services, preceded his official duties by going on Fox News a few hours after Rogers, the full committee chairman. Crenshaw told Fox that “instructions on who to target and how to target were coming from Washington without any debate.”

Actually, that’s a matter of considerable dispute.
