Presumptive Republican nominee Donald Trump held a rally in Albuquerque, New Mexico Tuesday. Outside the event, a large group of liberal activists and illegal aliens caused a near-riot attempting to shut down the event.

The mob, holding anti-Trump signs and Mexican flags, began throwing rocks and bottles at police on foot and horseback.

This is how the event unfolded on social media.

Protestors are now throwing bottles and rocks at our Police Horses.
