Speaking to reporters by Air Force One in Geneva, Joe Biden has expressed regret for some sharp words to a journalist who questioned him about the success of his summit with Vladimir Putin. Frustrated by a question asked by CNN reporter Kaitlan Collins at the end of his press conference, he told her she was 'in the wrong business'. Biden later apologised for being 'short', adding: 'To be a good reporter, you’ve got to be negative. You’ve got to have a negative view of life ... you never ask a positive question'
