Former Gov. David Paterson claims he was discriminated against and blocked from his law school alma mater Hofstra University because he supported opening a casino near the school on Long Island.

Paterson, who now works for Sands Casino, claims Hofstra even blocked nonprofits from using campus facilities over their support for a gaming facility at the Nassau Colliseum hub — which the school has fiercely opposed.

Paterson also said the members of the groups mistreated by Hofstra happened to be predominantly black.

“They were all black events,” Paterson — the state’s first black governor — railed to The Post. “They [Hofstra] crossed the line.”
