Scott Wiener and Connie Chan clashed over AI regulation in a debate for the San Francisco congressional seat being vacated by Nancy Pelosi. Wiener apologized for his campaign’s AI chatbot mimicking Chan, while both candidates argued they would protect workers and the public from AI’s harms.
In their first pre-election debate, Democratic House candidates Scott Wiener and Connie Chan agreed that AI companies should not regulate themselves, but challenged each other’s records and proposals. Wiener cited his AI safety legislation and criticized Chan’s record; Chan called his law watered-down and said he was beholden to tech companies. She proposed a moratorium on data centers and a role for workers and unions in regulating AI.
Wiener apologized during the debate for his campaign’s chatbot mimicking Chan. The candidates also differed over housing and labor, while agreeing on universal health care coverage and opposing sending U.S. troops to Taiwan in the event of a Chinese attack. Chan had Pelosi’s endorsement; Wiener had won the June primary with more than 40% of the vote, ahead of Chan, who received just under 30%.
