 I'm Rebecca Kesby, host of BBC NewsHour. As J.D. Vance is named as Trump's running mate, we speak to his college roommate, a Kenyan serial killer charged with 40 murders described as a vampire by police. And we go to a unique rainforest in Mozambique, now a conservation area. BBC NewsHour comes up in just eight minutes from now at nine o'clock here on Maine Public Radio.
