Washington Monument lights go out, investigation underway

Users took to social media to speculate on the reason for the mysterious outage

The Washington Monument lights went out on Sunday, leading officials to try and figure out why. 

"The exterior lights of the Washington Monument are currently out," the National Park Service tweeted on Sunday evening. "We are investigating and will have them restored as soon as possible."

Users took to social media to speculate on the reason for the mysterious outage, which appeared to leave the famed monument in darkness -- besides its red lights at the top that blink a warning to aircraft.
