(CNN) - The morning after Hillary Clinton attacked Barack Obama over his relationship with William Ayers, founder of Weather Underground, her campaign advisers struggled with questions over her view of pardons for members of that group issued by her husband, former President Bill Clinton.
On a conference call with reporters, spokesman Howard Wolfson said he did not know where the New York senator stood on the pardons, but that he would check.
The Obama campaign has responded to Clinton’s questions to the Illinois senator at Wednesday night’s ABC debate with press releases pointing to the former president’s pardons of Weather Underground members Susan Rosenberg and Linda Evans.
The group, which formed in the 1960s, sought the overthrow of the U.S. government, and carried out violent attacks including bombings.
