Today is Columbus Day. I sure hope you\u2019re spending it in celebration, maybe some rest too.\xa0\n\nRegardless, today we are going to remind ourselves of the incredible story of Douglas Seymour MacKiernan. It\u2019s part of the series I like to do on holidays, to highlight my brothers and sisters at the CIA who have died in line of duty \u2014 I want to share their lives and their sacrifice.\n\nAnd Douglas Seymour MacKiernan, what an example of that.\xa0\n\nFor decades no one knew his story. And that\u2019s not surprising, he worked undercover.\n\nBut this morning we should talk about him. Because it\u2019s an extraordinary story, not only for the time in which he lived but for us too.\n\nBecause the enemy that he faced \u2014 Communist China \u2014 is the same one that we face today.\n\nSo come with me on this journey, one that starts in Mexico City, onward to Massachusetts, then ends on a patch of frozen ground in China, just a few feet shy of what would have been Doug MacKiernan\u2019s freedom.\n\nAll that, plus what Doug\u2019s life means for America now, on this special edition of the President\u2019s Daily Brief. We\u2019ll be right back.\nLearn more about your ad choices. Visit megaphone.fm/adchoices
