Porn plays on screen during rush hour in D.C.'s Union Station

WASHINGTON -- Visitors at Washington's Union Station got an X-rated surprise when pornographic videos began streaming on a digital advertisement board there. 

One Twitter user wrote that "the monitors at Union Station just started playing Pornhub" during rush hour Monday, CBS affiliate WUSA-TV reports.

Beverley Swaim-Staley, president and CEO of the Union Station Redevelopment Corporation, confirmed an ad board near the Metro train entrance played pornographic videos Monday. The video lasted for a few minutes before someone was able to turn the board off.

Swaim-Staley says they're working with the company that leases and manages the property to determine if the display was hacked. Until they're able to identify the cause, the screens will remain off. 

The boards were recently installed inside the station as part of a renovation project to update the building. The displays can be turned off manually, but the videos are sent to screens remotely.
