Race to the White House: Trump's campaigning machine

This week, as the US gears up to vote for its new president, we take you behind the scenes to see how Republican nominee Donald Trump is drumming up some last-minute support. We also look at how the first South American pope is playing an increasingly important role in bringing about peace across the continent. Finally, we bring you a special report from New York, where the UN's own expert finds that the organisation’s response to the cholera outbreak in Haiti has been "disgraceful".
