Michael Jackson's personal physician pleads not guilty to a charge of involuntary manslaughter.
Prosecutors say Dr. Conrad Murray's gross negligence killed the singer.
Defense lawyers say they're confident Dr. Murray will be acquitted at trial and that they're not interested in a plea bargain. They suggest Jackson administered the Propofol himself while the doctor was out of the room.
A trial date has been set for March 28. If convicted, Dr. Murray faces up to four years in prison and may never be able to practice medicine again.
