As recovery crews endure cold water and miserable rain Friday to attempt to pull more wreckage of American Airlines Flight 5342 and an Army Black Hawk helicopter from the Potomac River, investigators are intensifying their search for the collision’s cause – with initial concerns already raised about the path of at least one of the aircraft.

A passenger jet hit an Army helicopter with three soldiers as the plane got ready to land at Reagan National near Washington, D.C.

The president also blamed the Biden and Obama administrations for the overnight plane crash in Washington, D.C., where there have been no reported survivors.
