If I were the president of the United States, I would be embarrassed by this. I would be ashamed to have to admit that this was my director of the FBI, Muekler obviously knows less than nothing about the investigation, who conducted it at the IRS or why.
Hells bells! He can't even tell who his own lead investigator is or how many FBI agents are involved, because he admittedly does not know!
This is great! Washington has gone from plausible deny-ability to "I don't know!"
