Have investigations, the Benghazi hearing with the three whistle blowers came to mind, and the public get to see Dems making political hay while Repub trying to get the whistle blowers to tell the facts.
I think the Administration’s self-immolation is far more effective than if the Republicans start screaming OMG OMG look at the fire, the WH is ablaze with scandals. The media is starting to run with this, if Republicans start screaming, they might go back into protective mode.
