“A vital book for understanding the still-unfolding nightmare of nationalism and racism in the twenty-first century.” —Francisco Cantú, author of The Line Becomes a River

Stephen Miller was one of the most influential advisors in the White House. He crafted Donald Trump’s speeches, designed immigration policies that banned Muslims and separated families, and outlasted such Trump stalwarts as Steve Bannon and Jeff Sessions. But he’s remained an enigma.

Until now. Emmy- and PEN-winning investigative journalist and author Jean Guerrero charts the thirty-four-year-old’s astonishing rise to power, drawing from more than one hundred interviews with his family, friends, adversaries and government officials.

After being radicalized as a teenager and attending Duke University, Miller served Tea Party congresswoman Michele Bachmann and nativist Alabama Senator Jeff Sessions. Recruited to Trump’s campaign, Miller met his idol. Having dreamed of Trump’s presidency before he even announced his decision to run, Miller became his senior policy advisor and speechwriter. Together, they stoked dystopian fears about the Democrats, “Deep State” and “American Carnage,” painting migrants and their supporters as an existential threat to America. While Trump railed against illegal immigration, Miller crusaded against legal immigration. He targeted refugees, asylum seekers and their children, engineering an ethical crisis for a nation that once saw itself as the conscience of the world. Miller rallied support for this agenda, even as federal judges tried to stop it, by courting the white rage that found violent expression in tragedies from El Paso to Charlottesville.
