Chad Benson fills in for Jim Geraghty today. Grab a stool as we serve up three impeachment-related martinis. Chad and Greg respond to Nancy Pelosi demanding articles of impeachment to be drafted against President Trump. They also wade into the firestorm over a constitutional law professor invoking Trump’s 13-year-old son Barron during her pro-impeachment testimony.
