On the Hunter Biden thing, since someone inevitably brought that up. According to the Ukrainians there never was any plan to investigate him, there was no evidence or reason they were aware of to bring a case, under that prosecutor or any other. Zelensky even refused to open such an investigation as spurious when directly threatened with withholding US aid as explicit coercion to do so.
Since you're so deeply concerned about US coercion of Ukraine for the personal political advantage of US politicians, I'm sure Trump's blatant attempts to do so as confirmed by several members of his own administration are particularly outrageous to you. Strange that you didn't mention it.
