Friday night's storm knocked down trees and power lines, and left millions of people without power. Virginia Gov. Bob McDonnell declared a state of emergency Saturday, saying the incident is the largest non-hurricane power outage in Virginia's history.
McDonnell says he received a call from Obama and was assured Virginians have federal support for all of the resources needed to recover from the devastation.
McDonnell also confirmed 6 deaths in Virginia, all of which were caused by fallen trees.
In the D.C. region, an estimated 2.5 million people lost power in Friday night's storm. In Fairfax, Virginia's largest county, 60 percent of residents lost power.
