Talal Chaudhry is using the report as fact that Nawaz Sharif's name was not in the news report and saying that report should not be changed now. Kashif Abbasi rebutted this argument by pointing out many other reports have been published as well.
I wouldn't dismiss Noorani's story right away. He has been right in the past but he is no one to pass the judgement on whether Nawaz Sharif is responsible or his children. Remember under NAB law, public office holder has to be responsible for children's wealth.
