Overview
- Guido Reichstadter has stayed on the arch for four days after climbing the 168‑foot Frederick Douglass Memorial Bridge and signaling he might come down sooner.
- Authorities kept a safety perimeter in place as lanes reopened to vehicles while the pedestrian walkway stayed closed, according to regional transportation officials.
- Reichstadter draped a large black banner, pitched a small tent, and wore an “END WAR” shirt to highlight his calls to stop U.S. operations in Iran and to oppose advanced AI.
- He reported running out of water and a low phone charge, yet said he could remain longer as police negotiators and fire crews monitored the situation from below.
- The Stop AI co‑founder has a record of high‑profile protests and faces a trial this month over an alleged action at OpenAI’s offices.
