The U.S. Congressional Police judged a military unit's drop demonstration at a nearby baseball field as an 'aircraft threat' and issued a temporary evacuation order to Congress.
The aircraft was a US military aircraft, with US paratroopers capable of demonstrating parachutes aboard the plane.
Congressional police issued an evacuation order to the U.S. Congress at 6:30 p.m. local time on the 20th, saying they are tracking aircraft that could pose a threat.
There was no specific threat, but it was explained as a precautionary measure.
The aircraft circulated around Washington after takeoff from Andrews Air Force Base in Maryland, the Associated Press reported.
The aircraft carried US paratroopers who were about to demonstrate parachuting down to Washington Baseball Stadium, about a mile from Congress.
Police later announced that the situation was 'closed', saying, "There is no threat to Congress."
