U.S. Capitol Evacuated Over Washington Nationals' Pre-Game Festivities

The adults are back!

An emergency evacuation took place at the U.S. Capitol on Wednesday when an unidentified aircraft, deemed a 'probable threat' by the Capitol's security, sailed over the complex.

Capitol Police escorted officials out as they awaited additional information on the potential danger.

It turns out the aircraft was part of the Washington Nationals' pre-game festivities, which featured U.S. Army Golden Knights descending into the stadium on parachutes.

WATCH:

According to the AP, "a twin-engine plane took off from Joint Base Andrews in Maryland and had been circling inside heavily restricted airspace close to the Capitol when the alert was sent."

Nationals Park is located roughly a mile from the Capitol.

The Capitol held its security amid the evacuation (around 6:50 p.m., EST) but reportedly did not call on its defense systems to target the aircraft.

Capitol Police states that they were not alerted of the pre-game demonstration.

The Nationals proceeded with Wednesday's game as scheduled, taking on the Arizona Diamondbacks.

The D-Backs are up, 8-0, at the top of the fifth.
