A hearing on actress Rose McGowan's upcoming trial on a drug charge has been postponed due to a prosecutor's scheduling conflict.

Police say McGowan's belongings — left on a January 2017 flight arriving at Washington Dulles International Airport — tested positive for cocaine. She's been charged with felony possession of a controlled substance and has said she intends to plead not guilty.

WTOP-FM reports that this week's preliminary hearing has been rescheduled to March 21. McGowan's attorney told WTOP that prosecutors asked for the continuance.

McGowan has been a leading voice against sexual harassment in Hollywood, accusing producer Harvey Weinstein of rape.
