Medvedev called Biden a threat to humanity after words about Putin. Medvedev clarified that Biden, who has “fallen into insanity,” poses a threat because he is ready to start a war with Russia.

Earlier, Biden once again spoke rudely about Russian leader Vladimir Putin during a closed campaign event in San Francisco, calling him a “son of a bitch.” The Russian leader's press secretary, Dmitry Peskov, called Biden's boorish statements about Putin a disgrace for the United States.
