COLBERT: “Back in March of 2018, Bolton almost wasn’t hired in the first place. Apparently, Mr. Trump hesitated, in part because of his negative reaction to Mr. Bolton’s walrus-style mustache. Ironically, while Bolton is leaving, the mustache is staying on as Stephen Miller’s new hairpiece. It’s youthifying. Trump promised, “I will be naming a new national security advisor next week.” Who will it be? Well, we know Trump picked Bolton because he saw him on Fox News. So get ready for National Security adviser, My Pillow guy.”
