Blow by blow: Clinton, Trump face off in second debate

With less than a month left before the US elections, Hillary Clinton and Donald Trump are pulling no punches as they head into the second presidential debate on Sunday night at the Washington University in St. Louis, Missouri. The “town hall” style debate follows Friday’s revelations about candidates – Trump’s crude remarks about women during a television shoot in 2005, published by NBC, and hacked emails that included Clinton’s Wall Street speech transcripts, published by WikiLeaks.
