To talk more about REAL IDs, what they are, and what purpose they’re meant to serve, The 21st was joined by a professor of computer science who's won awards for his research on airport security.

We check in with Rep. Darin LaHood about trade, agriculture, and Secretary Kirstjen Nielsen's resignation from the Department of Homeland Security. Plus, it's been about a month since a Boeing 737 Max 8 crashed in Ethiopia—so what's changed for Boeing since then? We'll also learn about the new 'Real ID' driver's license additions that will be required for domestic air travel starting next fall, and hear from you about your favorite fish fries in Illinois.

Illinoisans can now get driver’s licenses and state ID cards that comply with Real ID, the strict federal security requirements that will soon be needed for air travel.

You may have heard rumors that, as an Illinois resident, if you were planning to board a plane anytime soon, you'd better hurry and get a passport because the state's drivers licenses don't meet federal Real ID standards. As Amanda Vinicky reports, never fear. You're all good.
