The campaign's original response was the nonsense about the official schedule. This politico reporter managed a better response:
"Biden’s campaign would not rule out the possibility that the former VP had some kind of informal interaction with Pozharskyi, which wouldn’t appear on Biden’s official schedule. But they said any encounter would have been cursory. Pozharskyi did not respond to a request for comment."
Isn't it amazing? Speculative past tense! "Would have been"!
Why wouldn’t Biden just simply deny the story if the meeting never took place?
