‘Threatening’ aircraft prompts brief US Capitol evacuation

"The US Capitol was evacuated for a short time after police said an unidentified aircraft could
pose a threat. A top lawmaker later clarified that the incident was the result of a lapse in communication between federal agencies. The US Capitol Police issued an alert to lawmakers and congressional staffers around 6:30pm local time on Wednesday evening, saying a plane was spotted over the area which posed a “probable threat” and ordering a full evacuation of all buildings at the complex."
