I think he’s already told a lot. He would be a terrible witness, but I bet Huma is about to sing.
I would love to have videos of Hillary ratting out Obama to save herself.
If the Perve's testimony can be verified, he would be a credible witness. I doubt Huma would turn against Hillary. She is like Webster Hubble who once said he'd "take it again for the team", or words to that effect. Then there is Sandy Berger who stole damaging docs regarding the Clintons from the National Archives and has disappeared. I still don't understand why he wasn't prosecuted when caught red-handed. There was no way to parse, spin, re-direct when caught with the documents in his pants.
