Todd Blanche is doing a virtual impossibility: compellingly demonstrating that a person has not just lied, for we all have lied, but that he is a liar, that that is what the person is, a liar. His name might as well be Michael Liar (A lawyer cannot call a witness a liar, at least not in Florida state courts.). What hasn't Cohen lied about? When hasn't Cohen lied? That is what Blanche has done with these extremely attentive, highly intelligent, reporters.
