Brooklyn College is feeling the green after hosting Bernie Sanders’ presidential kickoff rally.

The school, part of the public City University of New York system, charged the Sanders campaign $70,000 for the March 2 event.

The rally attracted about 13,000 people to the Midwood campus, where Sanders, a Brooklyn native seeking the 2020 Democratic nomination, attended school for a year.

A CUNY spokesman said its campuses could be used during off hours by outside groups, but organizations would be charged fair market value and expenses for “partisan political use.”

A Brooklyn College spokesman said the money covered expenses such as security and that “a portion of the fee will be reinvested into upkeep of our facilities.”

The campus, noted for its broad lawns and Georgian buildings, has been in disrepair and even the clock in its iconic tower broke down last year.

A student started an Instagram page called @cuny_brokelyn_college and invited students to submit photos of crumbling facilities in order to bring attention to the need for repairs.
