"Virginia's voter registration deadline has been extended until Thursday, October 15 at 11:59 p.m. [3:59 a.m. GMT]," Northam said via Twitter on Wednesday.

The Virginia Department of Elections said the state’s voter registration system went down on Tuesday - the last day for residents to register before the November 3 presidential and general elections - as a result of a cut cable.
