should have simple, factual answers but the other party refuses and instead uses a lot of words to dance around giving a direct answer.

Yes, but some questions aren't simple "yes or no" questions. For example, one Republican asked, "Do you support it being legal to abort an unborn child up to the moment of birth?" That's not really a yes-or-no question, and I think it's a poorly framed one.

Even where abortion is legal, there are generally legal limits, often somewhere between 4 and 24 weeks, depending on the jurisdiction. If a woman chooses to continue the pregnancy, she's not going to reach her due date and suddenly decide, for absolutely no reason, "I'm going to have an abortion." If she decided she didn't want to raise the baby, she would give birth and place the child for adoption. The only situations where an abortion that late in a pregnancy occurs are severe medical emergencies, where doctors are trying to save the mother's life or address a catastrophic pregnancy complication.

So, that question is, in my opinion, misleading and doesn't have a simple "yes or no" answer. If you watch the hearing, the witness starts to answer the question, and then the politician interrupts them. How can you know what their answer was if they aren't allowed to finish?

The mature thing to do in a conversation is to let someone answer the question. If they dance around the answer, then say, "Okay, I hear you, but you didn't actually answer my question, so let me ask it again." But if I start to answer and only get half a word out before you interrupt me, that's not how you have a conversation. They don't even have time to dodge the question.
