A Florida-based activist who camped out atop one of Washington’s bridges for five days has ended his protest vigil. Guido Reichstadter came down Wednesday morning, ending his stand against AI and the war in Iran. Reichstadter was seen coming down from one of the arches of the Frederick Douglass Memorial Bridge where he had been camped since May 1. His presence caused periodic traffic jams as Washington police closed lanes and negotiated with him.
