They know Republicans would continue to spout nonsense about them. That is why they would only testify in public in front of cameras. I'm not a huge fan of the Clintons but they are a lot smarter than those politicians who love playing "gotcha."

Agreed!!

The main drawback to this is the ways it would be twisted by right wing media and influencers and no effective means of counteracting the twists. With either closed door or open testimony with Congress the same happens, but it’s easier to contain the damage.

I think it’s mostly to expose the hypocrisy; Comer never threatened anyone else with contempt of congress for not testifying.
