In a civil or criminal case, evidence of the following is not admissible against the defendant who made the plea or participated in the plea discussions:
(1) a guilty plea or admission of the charge that was later withdrawn;
(2) a nolo contendere plea;
(3) an offer to plead to the crime charged or to any other crime, made to one with authority to enter into or approve a binding plea agreement; or
(4) a statement made in connection with any of the foregoing withdrawn pleas or offers to one with authority to enter into a binding plea agreement or who has a right to object to, approve, or reject the agreement.

The court may admit such a plea, offer, or statement:
(1) in any proceeding in which another statement made during the same plea or plea discussions has been introduced, if in fairness the statements ought to be considered together; or
