Who owns Zardari's statement?

Former President Asif Ali Zardari's statement has become a mystery. Pakistan People's Party (PPP) has decided to investigate it. PPP's Secretary Information Qamar Zaman Kaira said that the party was investigating its origin. Opposition leader Khursheed Shah and Qamar Zaman Kaira visited National Press Club. On this occasion, Kaira said that Asif Zardari and PPP's stance was same that we stand by the army.
Everyone had commended General's decision, Kaira said, asking why only PPP is held accountable. Some of Rangers' excessive powers were mentioned by us and there was an outrage. In Punjab, only a signal was given and everyone including CM spoke out. CM Sindh also pointed out institutions' disability, he said. He said that PML (N) was exempted from laws. Going home and getting murdered by courts was only for us," Qamar Zaman Kaira said.
