Sunday on PBS News Weekend, as Capitol Hill haggles over border security measures, we get the latest from Arizona, where migrant crossings are hitting record highs. Then, how the process for college financial aid is changing and how it's affecting students and parents. Plus, the legacy of Supreme Court Justice Sandra Day O'Connor and her work to end the practice of electing state judges. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders
