Reply #116: That phrasing of the 5th is hugely relevant

[Joffan]

"nor shall be compelled in any criminal case to be a witness against himself"

and that is not at all what is required. No-one's asking her to be a witness against herself. Immunity for full and accurate testimony would ensure this.

I'm pretty sure that the general principle that any sworn testimony can be used for criminal proceedings ensures that the Senate hearings are indeed covered by the 5th amendment, despite wishful thinking elsewhere in the thread.
