Donald Trump 'very troubled' by Tulsa police shooting

Donald Trump said he was "very troubled" by last week's fatal shooting of a black man by a white police officer in Oklahoma, as he made a fresh appeal to black voters who have supported Democrats in the past by overwhelming margins.

Mr Trump appeared at an event with one of his top black supporters, Pastor Darrell Scott, at the minister's New Spirit Revival Centre, where the Republican nominee was introduced by boxing promoter Don King.
