Part one: Perry adviser responds to allegations he leaked sexual harassment story against Cain

Moreover, they accuse one of Rick Perry's key campaign aides of leaking the story to the press in an effort to sink Cain's candidacy.

CNN chief political analyst Gloria Borger speaks with that aide, Curt Anderson, in the first TV interview since the allegations were leveled. See part one of the interview here.
