"Bernie identified it himself," said Tad Devine, a senior adviser to the campaign, adding that Sanders looked at a digital image of the photo. "He looked at it — he actually has his student ID from the University of Chicago in his wallet — and he said, 'Yes, that indeed is (me).'" Sanders, a U.S. senator from Vermont, was traveling Friday near Reno, Nev., on the eve of the state's Democratic presidential caucuses.
