Anthony Romero had led the ACLU for only four days when the attacks of September 11, 2001 presented civil libertarians with their greatest challenge in decades. Since then, Romero and the ACLU have waged a continuous struggle in the nation's courts to ensure that the Constitution does not become a casualty of the war on terror. A son of Puerto Rican parents, and the first member of his family to graduate from high school, Romero earned law and public policy degrees at Stanford and Princeton. He is the sixth director to lead the ACLU since it was first founded, to combat the abuses of civil liberties that arose during the First World War. Romero has presided over the most explosive growth in the group's history, doubling its national staff and tripling its budget, enabling it to win significant court victories in defense of personal liberties, and restraining the warrantless surveillance of American citizens. He tells the story of this campaign in his book In Defense of Our America: The Fight for Civil Liberties in the Age of Terror.
