Donald Trump blamed his 2020 defeat on Democrats and the “deep state”—a supposed secret cabal of Washington insiders that relentlessly encroaches on the individual rights of Americans—for stealing the election and undermining his presidency. Most Americans who supported him agreed. Americans on the left increasingly fear the “military-industrial complex,” a faction of generals and defense contractors who they believe routinely push the country into endless wars. But does the American “deep state” really exist? This question is fundamental to preserving the legitimacy of American democracy, as frustration with and distrust for the government continue to grow. In Deep seeks to dispel these pernicious myths through an examination of the FBI, CIA, and Justice Department scandals of the past fifty years from the Church Committee’s exposure of Cold War abuses to the claims and counterclaims of the Trump era and the relentless spread of conspiracy theories online and on air. It exposes the misconduct of Attorney General William Barr; how distrust of the “deep state” undermined the US government response to the COVID-19 pandemic; and the growing discord sowed by the explosion of false information online. It investigates Trump’s quest to discredit government experts, the legislative and judicial branches, and the results of the 2020 election and assume authoritarian power for himself. “The idea of the deep state, Rohde writes, is inextricably linked to a particular view of presidential power” (Dina Temple-Raston, Washington Post). Based on dozens of interviews with career CIA operatives and FBI agents, “In Deep is a wholly satisfying read and a necessary one for anyone wanting to understand the forces at play in our government today” (Andrea Bernstein, Peabody Award–winning cohost of the Trump, Inc. podcast and author of American Oligarchs).
