On the eve of the 20th anniversary of 9/11, Preet was joined on Stay Tuned by former Secretary of Homeland Security Jeh Johnson. They discussed a topic that gets little media attention today, but was a source of political and legal wrangling for much of the early 2010s: the trial of 9/11 architect Khalid Sheikh Mohammed (known as KSM) and four other defendants involved in the attacks. 

Two decades after 9/11 and 11 years after war crimes charges were filed, there has still not been a trial held for the men who plotted the attacks. And no trial date has been set.

How did we get here?
