Jen Psaki sounds the alarm about the GOP's favorable response to Donald Trump's incendiary rhetoric, which increasingly mirrors the dehumanizing language of fascist dictators. The Atlantic staff writer, Mark Leibovich and ABC News Chief Washington correspondent Jonathan Karl discuss why Trump's base can't seem to get enough. Jen is also joined by George Conway and Claire McCaskill to break down the latest ProPublica story on Justice Clarence Thomas, who received gifts from wealthy conservatives after reportedly complaining about his personal finances in 2000. Jen also discusses Nikki Haley's prospects in the New Hampshire primary with the state's Governor, Chris Sununu, who endorsed Haley last week. Finally, Jen reflects on the tragedy that struck the Biden family in 1972, when Joe Biden's wife and baby daughter were killed in a car accident.
