In 2019, award-winning journalist Glenn Greenwald writes in this gripping new book, "a series of events commenced that once again placed me at the heart of a sustained and explosive journalistic controversy." New reporting by Greenwald and his team of Brazilian journalists brought to light stunning information about grave corruption, deceit, and wrongdoing by the most powerful political actors in Brazil, his home since 2005. These stories, based on a massive trove of previously undisclosed telephone calls, audio, and text shared by an anonymous source, came to light only months after the January 2019 inauguration of Brazil 's far-right president, Jair Bolsonaro, an ally of President Trump. The revelations "had an explosive impact on Brazilian politics" (The Guardian) and prompted serious rancor, including direct attacks by President Bolsonaro himself, and ultimately an attempt by the government to criminally prosecute Greenwald for his reporting. "A wave of death threats--in a country where political violence is commonplace--have poured in, preventing me from ever leaving my house for any reason without armed guards and an armored vehicle," Greenwald writes. Securing Democracy takes readers on a fascinating ride through Brazilian politics as Greenwald, his husband, the left-wing Congressman David Miranda, and a powerful opposition movement courageously challenge political corruption, homophobia, and tyranny. While coming at serious personal costs for himself and his family, Greenwald writes, "I have no doubt at all that the revelations we were able to bring to the public strengthened Brazilian democracy in an enduring and fundamental way. I believe we righted wrongs, reversed injustices, and exposed grave corruption." The story, he concludes, "highlights the power of transparency and the reason why a free press remains the essential linchpin for securing democracy."
