Yeah, they are. For Biden to pressure Ukraine to fire the lead prosecutor investigating his son, the prosecutor would have to be investigating his son.
So your argument is this unsourced quote you provided is evidence they were not investigating Hunter Biden? What?
It's from George Kents opening statement today. He's the "Deputy Assistant Secretary of State for European and Eurasian Affairs". And yeah, it's evidence that when Ukraine fired the prosecutor, the Burisma investigation had been closed for years. I'd heard people say that before, but nobody as qualified.
