Trump National Golf Club in Loudoun County was vandalized overnight Friday, according to the Loudoun County Sheriff's Office.
The vandals spray-painted the word "Resist" on the course. "Resist" has become a credo of the anti-Trump administration movement.
According to LCSO, the fairway was damaged and rock were spray-painted red and orange. Empty jugs of bleach were also found.
Trump National D.C., located about 25 miles outside the District, was also vandalized shortly after Donald Trump was elected president last November.
President Trump brought Sen. Rand Paul (R-KY) to his Loudoun golf course on Sunday to talk health policy with the outspoken critic of the failed plan to repeal and replace so-called Obamacare.
The Senior PGA Championship is scheduled to begin at Trump National May 23.
The golf club is not open on Mondays, and no damage estimates were available.
The Loudoun County Sheriff's Office and U.S. Secret Service is investigating the incident.
An NBC Washington news chopper caught an overhead image of the damage.
