I wouldn't say "get on his case", but he did try to portray the prisoners on tape thing in a weird way, IMO. CedarDave was watching and maybe he can say if he would characterize it as such.
Naturally, whatever he was asked, Rumsfeld handled superbly and emphasized the end of this conflict is already written--we will prevail. The DU(h)ers may be distressed over this, but we and the innocent Iraqi citizens will rejoice when that is achieved.
