Washington (CNN) CNN and The Des Moines Register will not release their final Iowa caucus poll, the network announced Saturday. "A respondent raised an issue with the way their interview was conducted, which could have compromised the results of the poll. We were unable to ascertain what happened during this respondent's interview, and cannot determine if this was a single isolated incident," the network said in a tweeted statement. "CNN, The Des Moines Register and Selzer & Company aim to uphold the highest standards of survey research and therefore the partners decided not to proceed," the statement continued. It's unclear whether the issue occurred more than once or impacted other candidates.
