"When he opened the FBI investigation into Russia's election interference, Peter Strzok had already spent more than two decades defending the United States against foreign threats. His career in counterintelligence ended shortly thereafter, when the Trump administration used his private expression of political opinions to force him out of the Bureau in August 2018. But by that time, Strzok had seen more than enough to convince him that the commander in chief had fallen under the sway of America's adversary in the Kremlin. In Compromised, Strzok draws on lessons from a long career--from his role in the Russian illegals case that inspired The Americans to his service as lead FBI agent on the Mueller investigation--to construct a devastating account of foreign influence at the highest levels of our government. And he grapples with a question that should concern every U.S. citizen: When a president appears to favor personal and Russian interests over those of our nation, has he become a national security threat?" -- Publisher annotation.
