The US president, who is known for a tendency to go off script, made the comments at a San Francisco fundraiser
The Kremlin has accused Joe Biden of debasing himself and disgracing his country after the US president called Vladimir Putin a “crazy SOB” during a fundraiser in San Francisco.
Biden was talking about the climate crisis on Wednesday when he said: “We have a crazy SOB like Putin and others, and we always have to worry about nuclear conflict, but the existential threat to humanity is climate.”
