As we noted in yesterday’s Daily Grist, Sen. Thomas Carper (D-Del.) had threatened to put a hold on the confirmation of Stephen Johnson as head of the EPA. Carper is pissed about the Bushies’ refusal to study two alternatives to their "Clear Skies" legislation.

Well, today he’s gone and done it. "Carper said he would not lift the hold until the EPA gave him an ‘ironclad’ guarantee it would evaluate the other plans."

Stay tuned.
