"The airplane was on a perfect and routine line of approach to the airport," he wrote on his social media site Truth Social.
"The helicopter was going straight at the airplane for an extended period of time. It is a CLEAR NIGHT, the lights on the plane were blazing, why didn't the helicopter go up or down, or turn.
"Why didn't the control tower tell the helicopter what to do instead of asking if they saw the plane. This is a bad situation that looks like it should have been prevented. NOT GOOD!!! What a terrible night this has been. God bless you all!"
Dispatcher audio of aftermath of American Airlines crash released
Air traffic control audio has since been released from the incident, detailing the harrowing moment dispatchers witness the crash.
"The accident happened in the river. Both the helicopter and the plane crashed in the river," a man on the audio says.
"It was probably out in the middle of the river. Um, I just saw a fireball and then it was just gone. I haven't seen anything since they hit the river.
"But it was a CR-J [the type of plane] and a helicopter that hit, I would say a half-mile of the approach."
What’s the latest on the rescue operation?
During a press conference, DC Fire and EMS Chief John Donnelly said his team 'don't know' if they'll find anybody alive.
He went on to explain that weather conditions were making the rescue operation tougher.
"There is wind. There are pieces of ice in the water... And because there is not a lot of light, you are out there searching every square inch of space," he said.
"These are very tough conditions for [rescuers] to dive in."
