Volker has given us no reason to question his integrity and has nothing to gain by taking on this thankless job. On the other hand, Lanny Davis has given us much to question his motives. Any one who goes to this known partisan for representation in testimony before a Republican controlled committee is suspect. Think about it, the Clintons and the Democrats would love to see the UN and the Security Council continue their anti-American agenda.
I understand what you are saying but this isn't a choice between Volker and Davis for me, it's between the US Congress and Volker. Davis is an aside, though a curious one.
His behavior is suspect given what we know about Kofi and son. Volker appears to be either in cohouts with Kofi or he's sticking his head in the sand.
Methinks you are correct. If Lanny Davis is hanging around this case it is for one reason only - to make sure that none of the dirt splashes on the Clintons. He probably offered his services "for free". I wonder who is paying the "Bill".
Very perceptive on your part. Word to the wise, all that.
