This is about as stupid a line as you get. How much more proof beyond all the laptop emails do you need and the self admission of pay for play with Ukraine do you need for the answer to be Biden? Oh then there are all the Chinese connections.
In addition to the Bidens, we have the phenomena in which politicians of both parties enter politics with average incomes but leave politics with significant wealth. And - at least two or three times a week - we read stories of politicians or public employees funneling public money into organizations in which they or close friends or relatives have a personal interest. Why is Noonan not concerned about any of that?
