Mayoral candidate Andrew Yang has proposed a casino on Governors Island as a way to raise revenue for New York City’s recovery — a plan that would face immense obstacles if he were to pursue it as the city’s next leader.

“That casino would generate so much money it would be bananas,” Yang, a former entrepreneur who ran for president last year, said during a recent radio appearance on The Breakfast Club. “If the city could get that in place and harness some of that — that would be one of the engines of recovery.”

Governors Island is a 172-acre former military and Coast Guard facility in New York Harbor that is only accessible by ferry. It currently houses several restaurants and businesses, a large park and a National Monument in addition to swaths of open space.
