From the quotes I've read on this thread, I'd say that she might seek to do him harm.
I agree with those who say she's dangerous, but at the very least, she is a pathological liar, who would lie about any meeting he had with her.
The proof of that is that she's already done it.
If her marriage is in trouble as well as she has mentioned occasionally, I would say that there is really a deep well of anger there that now focused (wrongly I might add) on the President. It's too bad that she is going through all this on the world stage.
