All 67 people on board the plane and the helicopter were killed.
An American Airlines regional jet went down in the Potomac River near Washington, D.C.'s Ronald Reagan Washington National Airport after colliding with a U.S. Army Black Hawk helicopter on Wednesday night, with no survivors.
Sixty-four people were on board the plane, which departed from Wichita, Kansas. Three soldiers were on the helicopter.
The collision happened around 9 p.m. when the PSA Airlines Bombardier CRJ700 regional jet was on approach to the airport.
Sean Duffy, who was confirmed as the secretary for the Department of Transportation on Tuesday, added a post acknowledging the crash on X.
In the post, he noted that he was posting from the headquarters for the Federal Aviation Administration in Washington, D.C.
"I am on site at the FAA HQ and closely monitoring the situation," Duffy wrote.
Kansas Gov. Laura Kelly said she is "actively" in contact with authorities regarding the crash.
"My thoughts go out to those involved. I will share more information as it becomes available," she said on X.
The Bombardier CRJ700 regional jet was carrying roughly 60 passengers, according to Kansas Sen. Roger Marshall, who called the collision "devastating news of what can only be described as nothing short of a nightmare."
The plane is capable of carrying up to 70 passengers.
Vice President JD Vance released a statement on X saying that he is monitoring the situation.
"Please say a prayer for everyone involved in the mid-air collision near Reagan airport this evening," he said.
