I think this is the guy.
He needs to be brought in and asked specifically with whom he met each time he visited the WH and what was their conversation.
He needs to be asked if HE EVER discussed targeting Tea Party or other conservative groups with Obama. The if he says that he never did, then ask him why he didn’t.
Ask him when did he know that the IRS was targeting these groups. If he said he didn’t know, then ask him who then authorized over 90 agents to target them.
When I get a letter from the IRS, even if it’s for something informational, I cringe.
They’ll never tell the truth to Congress under oath.
