Dr. Arnie Klein: I Warned Michael Jackson About Propofol

ET’s Kevin Frazier exclusively sits down with Michael Jackson's former dermatologist Dr. Arnie Klein, who says he warned Michael about the dangers of the powerful drug that allegedly led to his death.

“I told him that it was very dangerous. I told him it was addicting. And, I told him that he really shouldn't be using it,” Klein says he told Michael about Propofol.

Klein says he didn’t know Jackson was allegedly using Propofol around the time of his death, but he says Jackson had told him in years past that he’d used the drug.
