Vice President Kamala Harris, the presumptive Democratic presidential nominee, is expected to interview several contenders to be her running mate, with a selection expected by early next week. Ed O'Keefe reports from Houston, where Harris is campaigning. In a combative interview at an event hosted by the National Association of Black Journalists in Chicago, former President Donald Trump questioned Vice President Kamala Harris's racial identity, falsely stating that the presumptive Democratic presidential nominee only recently "became a Black person." Nikole Killion reports.
