The Commission on Human Rights and the Taxi & Limousine Commission are looking into the complaint about an incident Monday in Manhattan.
Paul Bruno said the driver pulled over two blocks into the ride and told them to get out.
Bruno said the driver told them hugging wasn't allowed.
Driver Medhat Mohamed told the New York Post in Thursday's editions that things were heating up, and that was distracting him. He said he'd treat a heterosexual couple the same.
If it's determined Mohamed refused service on the basis of sexual orientation, he could face fines, suspension and or loss of his taxi license.
