Marilyn Garbanza is the head of the ethics department for Peter Florrick's campaign. She makes herself instrumental during his governorship. She reveals that she is pregnant, then in a later episode she reveals the name of the child to be Peter. She says it is the name of the unborn baby's father, which leaves Eli Gold to think it's Peter Florrick's baby. The father of the child is later revealed not to be Peter Florrick, but another man named Peter.
