WASHINGTON (AP) — The National Park Service says a faulty power supply was to blame for two recent breakdowns of the Washington Monument's elevator.
The park service says the power supply was occasionally causing elevated electrical current to flow to the elevator. When the current went over the limit, the elevator shut down as it's designed to do to protect people's safety.
The park service says that's what happened on Tuesday and again on Friday when the elevator broke down, causing the monument to close. The monument is open Sunday.
