Dr. Richelle Cooper resumed testifying Monday in Los Angeles as the trial of Dr. Conrad Murray enters its second week.

She said Murray told her he'd given Jackson the sedative lorazepam but didn't mention the anesthetic propofol.

Authorities contend Murray gave Jackson a fatal dose of propofol and other sedatives.

Cooper was on duty at Ronald Reagan UCLA Medical Center the day Jackson died. She has testified she gave paramedics permission to pronounce the singer dead at his rented mansion but he was brought to the hospital because Murray wanted resuscitation efforts to continue.

Murray has pleaded not guilty.
