Well it got a little confusing, for everyone.....I think Issa was shocked when he realized what had happened, that her testimony waived her rights. There was whispering and I think Issa mentioned it, but then excused her. Gowdy then got quite vocal said she had waived her rights, that she should be made to stand and testify. Issa abruptly overrode Gowdy and told her to leave the room.
They need to get their act together after the surprise speech. Possibly Plan A was to ask her certain questions, expecting the 5th for each one, since she had announced beforehand she would be taking the 5th. Now, after the speech and the answering of Issa’s question, Plan B may require different questions.
