A U.S. official tells CNN the phone of the co-pilot of Malaysia Airlines Flight 370 was on and made contact with a cell tower in Penang, Malaysia, about 250 miles from where the plane's transponder last sent a signal.

In an interview with CNN's Erin Burnett, Captain Mark Matthews, who heads the U.S. presence in the search effort, explains why the underwater robot returned to the surface earlier than planned.
