Hypothetical: A witness took an oath to tell the whole truth. The adversarial cross-examiner abruptly cuts off the witness's testimony in the middle of a statement, leaving the train of thought incomplete and possibly leading to a misunderstanding by the jury.

The witness wishes to finish that statement and more. Their objective is to fulfill the "whole truth" portion of their oath. What can the witness do during trial to fix this situation?

Can they appeal to the jury? Raise an objection? Or is the witness at the mercy of the (either side's) lawyers' whims? Does the witness have a right to finish their statement even though the cross-examiner has cut them off?
