VIDEO: Jermaine Jackson Calls Michael Jackson Drug Question Unfair

Jermaine Jackson deflected a drug-related question regarding his late brother, Michael Jackson, on The CBS Early Show Tuesday.

"Your brother's (heavy prescription) drug use was not a secret," CBS personality Harry Smith said. "Are there moments when the family says, 'What could we have done differently, what should we have done differently, how could we have avoided where we are now?'"

"I wouldn't call it that," Jermaine said, from a location in Vienna, Austria, where he was announcing an annual tribute concert in the Thriller singer's honor. "I wouldn't call it that because, as I (have) stated before, there was nothing that I saw of anything of that substance. So for you to say that question to me is really not fair."

He defended even asking about the drug questions by citing Michael Jackson's well-known track record of philanthropy and humanitarianism.

"There's tremendous speculation and talk in the media, but at the same time, look at the person he was," Jermaine said. "He was a wonderful person."

Jermaine's concert, called The Tribute in Memory of Michael Jackson, is slated for September 26 in front of Schoenbrunn Palace in Vienna.

Michael Jackson died after suffering a sudden cardiac arrest June 25 in Los Angeles; officials declared Jackson's sedative-induced death a homicide, but no charges have been filed.
