Things aren’t so clear cut. She can fail to remember, fake anger (”What difference does it make”) and otherwise run out the clock. Holder and Lerner and a host of other appointees did the same thing. Did they flat out lie, or did they just not tell the truth? Hillary would have no problem with either.
Don't let her. Ask her yes or no questions. Gavel the bitch down.
Make her have a melt down and freak out.
