Today has committed both assault and battery. Assault is the act of intentionally causing someone to fear that they are about to be harmed, while battery is the intentional harmful or offensive touching of another person without their consent. In this scenario, when Today pushed against Darwin and caused him to stumble and fall, he committed both assault (by making Darwin fear harm) and battery (by physically touching him in a harmful way).
