A group of legal experts, press freedom activists, journalists, and public figures filled a ballroom at the National Press Club in Washington, D.C., to organize international opposition to the United States government's extradition of WikiLeaks founder Julian Assange. For the Belmarsh Tribunal, United Kingdom parliamentarian Jeremy Corbyn flew more than 3,670 miles to speak in person on January 20, 2023. Other speakers flew in from Italy and Croatia. In fact, very few of the delegates on the tribunal organized by Progressive International were from the D.C. area.
