Bodies of two missing workers recovered after Baltimore bridge collapse

Four men who were working on the Francis Scott Key Bridge when it collapsed are still missing. Divers have also located a pickup truck in the waters of Baltimore Harbor. Meanwhile, the NTSB will examine the recorders for insights into why the container ship lost power and couldn't turn before ramming into the bridge. With much of the ship traffic in Baltimore Harbor halted, thousands of jobs could be affected. NBC News' Tom Llamas and Tom Costello report.
