President Joe Biden called Russian President Vladimir Putin “a crazy S.O.B.” in a fundraiser Wednesday in San Francisco, according to the pool reporters travelling with the US president.

Axar.az informs that CNN reported on this.

“We have a crazy S.O.B. that guy, Putin, others. And we always have to be worried about a nuclear conflict. But the existential threat to humanity is climate,” Biden told those gathered at the fundraiser.

Biden's verbal attacks against Putin have also sharply intensified at the White House and on the campaign trail. Last week, the U.S. President blamed Putin and "his thugs" for the death of opposition leader Alexei Navalny.
