“Such boorish statements from the mouth of the US head of state are unlikely to somehow offend the head of another state, especially President Putin.

But this is a huge shame for the country itself,” he told VGTRK journalist Pavel Zarubin.

Earlier, Biden once again spoke rudely about Russian leader Vladimir Putin during a closed campaign event in San Francisco.

In 2022, the US President, while visiting a Ukrainian refugee camp on the border of Poland and Ukraine, answered a question from a journalist who asked what he thought about Putin.

Responding, the head of the United States called the Russian leader a “butcher.”

The Kremlin said that Biden's insults against Putin further narrow the window of opportunity for improving Russian-American relations.

Also, the press secretary of the Russian President Dmitry Peskov reminded Biden that the leader of the state must remain sober.
