The new administration fired the FAA director, froze hiring of new controllers, disbanded the aviation safety advisory board, fired the head of the Coast Guard, and the head of the TSA (both on air safety boards), threatened the jobs then offered a fake “buyout” of all federal employees (including air traffic controllers) and now that the inevitable disaster struck with the first mid air collision in decades under two weeks later he’s trying to blame Biden (who had no mid air collisions during his administration and strengthened hiring), but is doing absolutely nothing to address the deadly problems he continues to create, in fact he is trying to fire more of the understaffed agencies employees.

Edit: Early indications suggest the helicopter was having communication issues and didn’t hear the warning about the approaching plane.
Also now known, the airport traffic control was understaffed to the point where one controller controlled both planes and helicopters, which is absolutely not normal procedure. There was an official FAA notice sent to the whitehouse of this shortage this week.
There was a press release 12 hours before the crash decrying the national shortage of FAA employees after the administration fired 100 FAA employees and offered the rest a fake “buyout”, and warning there would be an accident due to massive (over 33%) understaffing which was just exacerbated by anti inclusion and loyalty test policies.
