She testified under oath that she did nothing wrong. The committee is entitled to cross examine her on that point.
By making a statement after being sworn in, she has already testified on the issue of her criminality. Whoever advised her to read a statement after being sworn in committed malpractice. Her remedy is not to be subject to cross examination, but to sue her attorney for malpractice.
I would agree....that advice on how to handle the fifth was not understood at all. For anyone, who should ever get called in front of a grand jury or congress....if you think you are involved in something sneaky or illegal....from the minute you walk in....just keep to ‘no comment due to the fifth amendment’ routine. Don’t say anything else.
