It tells the incredible story of a German spy who infiltrated Congress in 1940-41, inducing two dozen congressmen and senators to spread Nazi propaganda in floor speeches, op-ed columns and constituent mailings. Simultaneously, armed extremist groups began training for a violent takeover of the country. In many ways, the eight-decades-old story is a disturbing forerunner of the Trump era.
