Episode 7: Mobilized

Rachel Maddow Presents: Ultra

With Republican Sen. Joseph McCarthy facing the most serious challenge of his political life -- a looming censure vote in the U.S. Senate -- McCarthy's most fervent supporters raise up an army to fight in his defense. The effort, which draws together mainstream Republicans and McCarthy's most radical followers on the ultra right, will involve threats of violence, harassment, and an armed show of force on the steps of the U.S. Capitol.
