More women in prison worldwide, what Mexico's doing to stop migrant flows and shipping water from Alaska to South Africa

President Donald Trump says Mexico isn't doing enough to stop the flow of migrants across the border. We'll do a bit of digging and find out what Mexico is doing. Also, we launch a new series from our Across Women's Lives desk called "Unequal Justice." It's an in-depth look at what life is like for incarcerated women around the world. Our first story comes from Ohio, where the opioid crisis has led to a growing number of women in jail, where they're now waiting for treatment or a second chance. Plus, why Sitka, Alaska, is thinking about shipping water to Cape Town, South Africa.
