Trump tells fractious convention 'we're going to win!'

Donald Trump tried to put the Republican convention back on track following a rank-and-file revolt, telling party delegates "we're going to win" the White House. Making a surprise cameo appearance on Monday at the gathering in Cleveland to introduce his wife Melania, the bombastic tycoon showed confidence that belied the day's spasm of public division. "We're going to win so big" said Trump.
