[A wife can’t testify against her husband & vice versa.]
Sorry, yes I had forgotten that. Lol, I lead a sheltered life!
Nothing to apologize for. It's not something one usually dwells on (unless one needs to I suppose).
I just think Blago's wife (I keep using that term because I don't know her given name) may be valuable to Fitzgerald in getting information out of Blago. She certainly seems culpable in all this.
