There is no pass on this one for Romney. If he was unaware it would be questionable. BUT...he was already aware that the contractor used illegals. Romney was able to confront the issue with the contractor last year when he gave him a second chance. Thats when it became his responsibility to insure that the contractor was keeping his word. If he could confront him that time there is no reason he could not question whether or not the contractor was true to his word. Apparently the man did not even change out the workers. To use the excuse I was too busy campaigning doesn’t cut it.
