Answer Self-Incriminating Questions or Be Fired

[...] if you decide to go ahead and answer questions, your answers can be used as a basis for discharging you from office, and they can be used against you in a future criminal prosecution. [...] if we decide to grant you official immunity - and we will tell you if we do - you become legally obliged to answer our questions, and you can be discharged and even prosecuted for refusing to answer them, though you cannot be criminally prosecuted on the basis of anything you say. [...] if you refuse on Fifth Amendment grounds to answer specific questions that an innocent person would be expected to answer, your refusals to answer can be used as evidence of misconduct, and, in combination with other evidence of misconduct, your refusals may suffice to discharge you from office.
