STORY: As U.S. President Barack Obama offered condolences to those who lost loved ones in the Amtrak train derailment, he called for infrastructure investment in a news conference following a meeting with Gulf State leaders at Camp David.
"We are a growing country with a growing economy. We need to invest in the infrastructure that keeps us that way, and not just when something bad happens like a bridge collapses or a train derailment, but all the time," he said.
