Any investigation better be legit, hate witch hunts of any form. There are SOME things that stand to be investigated, like the way the admin turned a blind eye to the Black Panthers, etc... but if they start looking at silly things, it will cheapen them.
I doubt the Republicans will look at silly things. There is real corruption on he political left with the banks. We need to appoint a speical prosecutor and have it all investigated and exposed. It will take a couple of years.
A legitimate target is the suit against Arizona.
