It’s Kai’s last day as a regular co-host of “Make Me Smart” and he’s got a solid rant (and two bleeps). We’ll get into the Trump administration’s push to block international students at Harvard, thretening one of American’s biggest exports: higher education. Plus, we’ll unpack the Supreme Court’s 4-4 split over a separation of church and state case. And, could penguin poop be a tool against global warming?

Here’s everything we talked about today:

• “Supreme Court deadlocks, blocking creation of first religious public school” from The Washington Post

• “Trump Administration Halts Harvard’s Ability to Enroll International Students” from The New York Times

• “Harvard University Loses Student and Exchange Visitor Program Certification for Pro-Terrorist Conduct” from the U.S. Department of Homeland Security

• “Stop making cents: US Mint moves forward with plans to kill the penny” from AP News

• “Penguin Poop Could Limit Global Warming’s Impact on Antarctica” from Bloomberg

“Make Me Smart” is going on a break! Kimberly and Reema will be back with new episodes June 9. We’d love to hear from you while we’re away. Email makemesmart@marketplace.org or leave us a voicemail at 508-U-B-SMART.
