Smitty at The Other McCain has this answer:
To answer Mr. William’s question, Holder is still the AG because he is both a Reliable Tool and, also, he Knows Too Much. My guess is that Holder has a signed presidential pardon in his safe. Would you exhibit the sort of cheek that Eric Holder offers before Congress without a Get Out Of Jail Free card in hot standby?Makes sense to me. I'm thinking about starting a pool among my conservative friends. Guess how many presidential pardons are issued for administration insiders between November and January 19, 2013. Closest to the correct number wins the pot.
