U.S. doesn't believe terrorism involved

The U.S. doesn't believe there's a link to terrorism in the Germanwings crash in France that killed all 150 people aboard the plane.

White House spokesman Josh Earnest, commenting Thursday on the crash, said "based on what we know, there is not a nexus to terrorism."

French investigators believe the co-pilot barricaded himself inside the cockpit and intentionally rammed the plane into a mountainside in the French Alps. Investigators believe the pilot had left the cockpit to go to the lavatory, leaving the co-pilot at the helm, and the pilot wasn't able to get back in.
