Sorry. But she was asked questions, after making her self-serving statement. She was asked to confirm whether certain documents were, indeed, what she had certified them to be.
She answered willingly.
She's SOL on the 5th Amendment.
The only time in that hearing Issa followed advice of counsel. That said... he should then have ruled she had waiver her 5th Amendment rights by so stating and answering. And the look of her attorney-— he knew it.
The next step, right then was to continue to ask questions, and then when she refused, cite her for contempt, actionable contempt. And.. firing. She must answer.
