Just once, I wish someone being sworn in would say - "No". I don't swear to tell the whole truth. And if you don't ask the right questions, because you're too stupid to understand the topic, I'm not going to help you out by volunteering information.
BTW, does freedom of speech give one a right to lie? Just thinking out loud.
Your last remark posits a very good question.
“Doesn’t Freedom of Speech include a freedom to lie?”
No one wants to answer that one.
