Same kind of baloney that the Nixon administration tried to push.
This is actually good news, because it means that some senior WH staff will get thrown under the bus. Eventually one of them might sing, like John Dean did.
Dean sang to save his skin at the expense of those who were under his command. His lies and BS were inaudible because they were covered up by the 64-part harmony accompaniment of the MSM, who loved every minute of his testimony.
If Obama has a John Dean, his every utterance will be covered up by wild pot-beating and blaring air-horns from the same MSM. He'll be very lucky not to end up with a bullet through his head, found along some trail in Rock Creek Park.
“Eventually one of them might sing, like John Dean did.”
What is needed is a Judge Sirica (Watergate fame) to give immunity/plea deals to guilty IRS agents and managers that talk and finger superiors.
Get some convictions going, and lips will start wagging.
