Also in the programme, Emily Means, a reporter with KUER Public Radio in Utah, tells us what to expect at the debate in Salt Lake City between Vice President Pence and VP candidate Kamala Harris. Plus, we'll take a look at a rocky day on the US markets with Susan Schmidt of Aviva Investors in Chicago.
