The politician wrote about this on the social network X (formerly Twitter).
“Contrary to what the US President said, the existential threat is not climate, but useless old men like Biden himself,” the report said.
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.
