After Trump teased an upcoming "big announcement" last week, Jon Stewart contemplates what news Americans are supposed to be so psyched for: the possible suspension of due process, Trump's appointment of Fox News host Jeanine Pirro as D.C. district attorney, Qatar's $400 million luxury jet "gift" for Trump, or lower prices on the "fat shot drug"? "Our character is the essential identity of us as people and us as a nation, and we've let it erode." Retired four-star general who served 34 years in the U.S. Army, General Stanley McChrystal, sits down with Jon Stewart to discuss his book "On Character: Choices that Define a Life." They talk about leading a national conversation on character, employing empathy in war to negotiate with ideological warriors and mercenaries, what upset him most about Defense Sec. Pete Hegseth's Signal chat leak, and how his wife taught him to live "with no use for the rear view mirror."
