Thorn in Obama's side Bill Ayers promoting new book tonight

Bill Ayers, the former Weather Underground radical whose tie to Barack Obama was a major attack point by Republicans during the presidential campaign, is here tonight with his wife, Bernardine Dohrn, reading from their book.

The couple, authors of "Race Coarse: Against White Supremacy," a collection of essays about structural racism in the criminal-justice system, politics and education, appear at 7 at the Arch Street United Methodist Church (Broad & Arch).

Ayers, Dohrn and and other members of the Weather Underground bombed various government buildings in the '60s and '70s. Obama and Ayers, now a University of Illinois professor, served on a nonprofit foundation's board together, and Ayers once hosted a party for Obama. Dohrn is the director of the Children and Family Law Justice Center and a professor at Northwestern University School of Law.
