President Joe Biden says he isn't confident the US election in November will be peaceful, due to previous comments by Republican contender Donald Trump. "I'm confident it will be free and fair. I don't know whether it will be peaceful," Biden tells reporters as he makes the first appearance of his presidency in the White House briefing room. "The things that Trump has said and the things that he said last time out when he didn't like the outcome of the election were very dangerous." SOUNDBITE
