Geoffrey Berman was honored to be tapped for the role of US Attorney for the Southern District by Donald Trump in 2018. But almost immediately, Berman found himself pushing back against the Trump Justice Department's blatant efforts to bring weak cases against political foes and squash worthy cases that threatened to tarnish allies and Trump himself. Holding the Line is a never-before-told account of the lengths Barr went to in corrupting the independence of the office, and the lengths Berman had to go in preserving it. It also relates the remarkable casework of the Southern District in Berman's time there, including taking down notorious sex traffickers Jeffrey Epstein and Lawrence Ray, Big Pharma executives, and repatriating Nazi-looted art. Riveting in themselves, these stories showcase the esprit de corps that makes the Southern District so special, and the stakes Berman felt in protecting its integrity against all foes, up to and including the US attorney general and the president of the United States.
