Tonight on PBS News Weekend, with measles cases steadily rising, questions about how the Trump

administration is dealing with the outbreak.

Then schools brace for the possibility of immigration arrest after President Trump's

decision to allow ice into classrooms.

And how scientists are using satellite trackers to help solve a mystery about one of the

world's oldest living creatures.

Our long-held assumptions about these animals may not be 100% correct, in part because

it's really hard to study them. It's very hard to find

them offshore. So we've improved the best available data.

Good evening. I'm John Yang. The growing measles outbreak in the southwestern United States
