In 1969 he co-founded the Weather Underground, a self-described communist revolutionary group that conducted a campaign of bombing public buildings during the 1960s and 1970s, motivated by US involvement in the Vietnam War. He is now a professor in the College of Education at the University of Illinois at Chicago, holding the titles of Distinguished Professor of Education and Senior University Scholar.
