Is it a material untruth. If not then not violation of immunity deal.
I don’t know. Until we have public hearings how can anyone know?
of course its material if he had a file did he delete it and when or does he still have it? hopefully for him he still has it and gives it up for leniency.
Doesn’t matter, if he had immunity, he has to testify and can’t be prosecuted for crimes before immuninty. But he has to testify and can not lie. If he lies in testimony he can be prosecuted for lying under oath.
If Obama pardons him, he can be called back again to testify next year. Again he has to tell the truth under oath and can not refuse to testify, because he has immunity.
