Jameel Jaffer is the Executive Director of the Knight First Amendment Institute at Columbia University. Under his leadership, the Institute has filed precedent-setting litigation, undertaken major interdisciplinary research initiatives, and become an influential voice in debates about the freedoms of speech and the press in the digital age.

Until August 2016, Jaffer served as deputy legal director at the ACLU, where he oversaw the organization’s work on free speech, privacy, technology, national security, and international human rights. He litigated some of the most significant post-9/11 cases involving human rights and national security, including cases relating to surveillance, secrecy, censorship, interrogation, detention, and extrajudicial killing. He led or co-led litigation teams that compelled the Bush administration to disclose the “torture memos,” compelled the Obama administration to disclose the “drone memos,” and compelled the National Security Agency to abandon its dragnet surveillance of Americans’ call records. He also played a major part in the ACLU’s decision to take on the representation of Edward Snowden. The New York Times described one of his transparency cases as “among the most successful in the history of public disclosure.”

Jaffer’s recent writing has appeared in The New York Times, the New Yorker, the Washington Post, and the Yale Law Journal Forum. He is an executive editor of Just Security, a national security blog, and his most recent book, The Drone Memos, was one of the Guardian’s “Best Books of 2016.” In recent years he has delivered the inaugural Peter Zenger Lecture at Columbia Journalism School; the ‘Or Emet Lecture at Osgoode Hall Law School; the Eva Holtby Lecture on Contemporary Culture at the Royal Ontario Museum; and the Salant Lecture on Freedom of the Press at the Harvard Kennedy School’s Shorenstein Center. He was named to Foreign Policy’s “100 Global Thinkers” list in 2012, received the Vox Libera award from the Canadian Journalists for Free Expression in 2015, and was inducted into the Newseum’s Freedom of Information “Hall of Fame” in 2016.

Jaffer is a graduate of Williams College, Cambridge University, and Harvard Law School, where he was an editor of the Harvard Law Review. He served as a law clerk to Hon. Amalya L. Kearse of the U.S. Court of Appeals for the Second Circuit, and then to Rt. Hon. Beverley McLachlin, Chief Justice of Canada. He currently serves on the board of the Pierre Elliot Trudeau Foundation, on the advisory board of First Look Media’s Press Freedom Litigation Fund, as a commissioner of the Canadian Commission on Democratic Expression, and on the advisory board for the Center for Democracy and Technology. He was a Distinguished Fellow at the University of Toronto’s Munk School from 2016 to 2021 and a Fellow at the Open Society Foundations in 2013.
