McCain surrogate: Michelle Obama should be questioned on Ayers ties.
John Murtagh, whose childhood home was firebombed by the Weather Underground, says on a McCain conference call that Michelle Obama should face questions on her relationship with Ayers and his wife.
"I would emphasize that we've all been focusing on Senator Obama. I think we need to speak to his wife."
Michelle Obama and and Ayers' wife worked at the same Chicago law firm beginning in the 1980s.
