The World

President Barack Obama and former President George W. Bush were in Dallas on Tuesday for a memorial service honoring the police officers killed in last week's ambush at a Black Lives Matter rally. Both speak to the racial divides plaguing the nation. Also, we'll have the story of a Liberian man who fled that country's civil war and came to America, but then decided to move back, in part because of the racism he faced in America. Plus, an international tribunal in The Hague has ruled that China's claim to much of the resources of the South China Sea has no legal basis.
