Biden apologises for snapping at CNN reporter: ‘I shouldn’t have been such a wiseguy’

President Joe Biden has apologised after snapping at a CNN reporter at a press conference following his summit with Russian President Vladimir Putin on Wednesday.

Asked why he was “confident” that Mr Putin would change his behaviour by CNN’s Kaitlan Collins, Mr Biden appeared agitated, responding: “I’m not confident.”

“Let’s get this straight,” the president said. “I said what will change their behaviour is if the rest of the world reacts to them and diminishes their standing in the world.
