Obama returns to the world stage to boost Biden and reassure leaders after four years of Trump
Barack Obama is headed to next week's big climate conference in Glasgow to try and convince the world that America is more about Joe Biden than Donald Trump.
At least when it comes to fighting climate change. And at least when you judge the country as a whole and not just what's going on in Washington, where the President's climate agenda just took a major cut in Congress.
It's an extremely unusual appearance by a former president at a world leaders event, but Obama aides and friends tell CNN the former President wants to help Biden win back world faith in American leadership on this issue, and get the global alliance back on track after four years of Trump.
