BRIAN WILLIAMS, anchor: In LA today , the trial of Michael Jackson 's doctor went on. The prosecution called its very last witness today, one of the leading experts on the powerful anesthetic propofol. The prosecution's case is expected to wrap up on Monday. Then it's the defense's turn. Sources close to the case say the defense will argue that Michael Jackson had taken an anti-anxiety medication just hours before his death and never told Dr. Conrad Murray . That, the defense will argue, is what killed Jackson , not the propofol.
