Imagine if Pelley had asked McCabe: Did the FBI investigate the origins of the dossier that prompted the Trump investigation? McCabe of course would refuse to answer but the look on his face would have been priceless. Eventually someone in the MSM will ask that question.
It was just a publicity tour. The MSM has a long track record of failing to follow-up with hard questions against their political allies. Probably one of the worst 60 minutes segments ever produced, as far as hard hitting journalism goes.
