Kathy Jorrie, who works for concert giant AEG Live, testified Wednesday at the involuntary manslaughter trial of Murray. She questioned some of the doctor's requests which included the possibility of hiring a second doctor to assist him.

Jorrie says Murray told her that Jackson was "perfectly healthy" and in excellent condition in the days before Jackson's death.

According to her testimony, Murray asked for a CPR machine in case it there was not one available at London's O2 arena. This is where Jackson's planned series of comeback concerts in 2009.

Earlier in the day, Paul Gongaware, an executive for AEG Live, the company who was promoting the concert series, said the singer appeared strong during one of his final rehearsals.

Murray has pleaded not guilty and faces up to four years and loss of his medical license if convicted.
