A pregame performance at a Washington Nationals baseball game featuring the Army's Golden Knights prompted a brief evacuation of the U.S. Capitol.
"The Capitol was evacuated out of an abundance of caution this evening. There is no threat at the Capitol. More details to come," police said in a statement.
The Golden Knights parachuted into the stadium, blocks from the Capitol, as part of Military Appreciation Night. There was a miscommunication between Capitol Police and the organizers of the pregame events, two Capitol Police sources said.
Initially, police ordered the building to evacuate, saying in an email to staffers at the Capitol, “The USCP is tracking an aircraft that poses a probable threat to the Capitol Complex.”
The Army acknowledged there were issues with the event.
"We are reviewing all aspects of the event to ensure all procedures were followed appropriately to coordinate both the flight and the parachute demonstration," Kelli LeGaspi, spokeswoman for United States Army Recruiting Command, said in a statement.
In a statement, House Speaker Nancy Pelosi, D-Calif., said the Capitol was evacuated due to the Federal Aviation Administration's "apparent failure to notify U.S. Capitol Police of pre-planned activities," and called for a review to determine what precisely went wrong.
"The Federal Aviation Administration’s apparent failure to notify Capitol Police of the pre-planned flyover Nationals Stadium is outrageous and inexcusable," Pelosi wrote. "The unnecessary panic caused by this apparent negligence was particularly harmful for Members, staff and institutional workers still grappling with the trauma of the attack on their workplace on January 6th."
Capitol Police said Thursday it's made aware of hundreds of authorized flights in the "restricted airspace" every week, calling the lack of coordination "extremely unusual."
“As soon as it was determined that we were not given advanced notice of an approved flight, our officers followed USCP policies and procedures and immediately led everyone safely out of the Congressional buildings," the agency said in a statement.
Alexandra Hejduk, a spokesperson for North American Aerospace Defense Command, said everything in regard to the flight was FAA compliant and “no fighter jets were scrambled,” adding that NORAD was not involved.
Congress is in recess this week, meaning most lawmakers are back in their home states and fewer staffers are usually around.
