Democratic presidential candidate Bernie Sanders on Monday released a campaign video that highlights his childhood in Brooklyn.

Sanders is interviewed by actor Mark Ruffalo as they walk through the Brooklyn College campus, where Sanders attended for a year before going to the University of Chicago.
“How much did it cost you to go to school here,” Ruffalo asks Sanders. “Much cheaper than it is today?”

“I would say that is an understatement,” Sanders says. “It is not a radical idea” to have free tuition at public colleges and universities he adds, speaking about one of his main policy proposals.
