"You just happened to be there at the end," Lemon said.
"Yes," replied Murray.
"Conrad Murray, as you sit here now in jail, do you believe you are innocent?" Lemon asked.
"Absolutely," Murray said. "No doubt."
"He's never wavered," his lawyer Valerie Wass added.
"Why am I innocent?" Murray continued. "Because I did nothing wrong and all I tried to do was to help a friend who I encountered in a devastated state and I tried to do everything possible to help my friend. I have been called names and who knows what. Nobody else was there at that time and I can say with the effort that I made I could've suffered a cardiac arrest myself. It was not an easy task but I never gave up on my friend -- never did."
Wass then stopped Murray from saying more that might relate to his criminal case, which she is appealing.
Murray: My trial was not fair
"I believe I was not given due process. I think the judge was not impartial. I think the district attorney did something that was so absurd. He altered evidence in open courtroom. Could you imagine that?" he told Cooper.
The evidence was prosecution exhibit 30, an empty propofol bottle that was allegedly placed in a makeshift IV configuration. Deputy District Attorney David Walgren pulled an unused tab on the bottle that was intended to hold the bottle on a stand. When investigators found it, it was not pulled.
"If I had to do this again, that's the one thing I would never do," Murray said. "I would never sit quietly in the courtroom and have a district attorney tear open and destroy the integrity of evidence when there was no reason to do that. That was not the only time. There were so many issues of irregularity and obstruction of justice on his part."
Murray: Michael was my great friend
Murray talked about his relationship with Michael Jackson in the last months.
"I've lost a friend, a great friend, a man who was imperfect like all of us are," he told Lemon. "He has had his dark sides and he has had his good sides and I've known them both."
His role in the friendship was to bring Jackson peace, Murray said.
"But as he left in a state of total absorption of all of the pains he has encountered and all of the stories that haven't been told that was important to him to either regurgitate, ruminate, whatever he wanted -- to think about an opportunity to release himself and I gave him that opportunity," Murray said. "There was an opportunity where Michael finally found an opportunity to tell someone almost anything and knew he was protected. I gave him that. I gave him that peace."
He expanded on this with Cooper. "To be honest, I became a sounding board for Michael," Murray said. "He offloaded and regurgitated everything that was bad in his past and everything that was dark. And I have been the absorbent capacity for that."
Murray: I love Michael's children
Murray asked to speak about Jackson's children, with whom he said he had "a beautiful, blessed relationship---an extremely good one."
"Prince Jr., Paris and Blanket are like my own kids," he said. "They are my children. I love those children. I worry about them."
"There are things I can share about the children, but I don't think I will go into that, not in this forum," he said. "But at the same time I hope the children are doing well, that they are looked after very well."
He then took aim at other members of the Jackson family, without calling names.
"I am pretty sure there are a number of bottom dwellers right now who are sucking up for anything they can, but I do hope the children will not fall victim of that," Murray said.
"The little boy that Santa Claus forgot"
Murray began singing after Cooper brought up the topic of the Jacksons' wrongful death lawsuit against AEG Live. He asked if he would testify on behalf of the Jacksons, who are seeking billions of dollars in damages for the singer's death.
