Update (1730ET): In addition to the tit-for-tat slur-trading, Russian President Putin told a Russian state television reporter:

"I've just thought of this now... I want to propose to President Biden to continue our discussion, but on the condition that we do it basically live, as it's called. Without any delays and directly in an open, direct discussion. It seems to me that would be interesting for the people of Russia and for the people of the United States."

A live TV debate? 

"I don't want to put this off for long. I want to go the taiga this weekend to relax a little," Putin said.

"So we could do it tomorrow or Monday. We are ready at any time convenient for the American side."

The Russian leader also said he wished Biden "good health."

"I would say to him: 'Be well.' I wish him good health. I say that without any irony, without jokes," Putin said.
