(Portland, OR) -- TEDxPortland organizers are apologizing after receiving backlash for allowing unaffiliated candidate for Governor Betsy Johnson to speak at the event. The surprise interview with Johnson during Saturday's event sparked criticism from participants due to the fact that other candidates for governor were not invited to speak. Johnson is a supporter of gun rights and said the style of guns doesn't dictate the lethality. She also called for better mental health care in Oregon. TEDxPortland organizers apologized for making Johnson part of the event.
