Transportation Secretary Sean Duffy will give remarks Tuesday afternoon providing an update on the probe into the January crash near Reagan Washington National Airport that killed more than 60 people.

The NTSB says the current helicopter routes around the busy airport "pose an intolerable risk to aviation safety" in the wake of January's collision that killed 67 people.

The deadly crash took place in January when a military helicopter collided with a passenger jet, killing 67 people.
