The top security guard for Donald Trump punched a protester in the face after the man chased him for snatching a banner Thursday.
The guard grabbed the blue sign that said "Trump: Make America Racist Again" outside a press conference on the Donald's new pledge of loyalty to the Republican Party, NY1 Noticias video shows.
Demonstrator Efrain Galicia ran after Schiller and appeared to reach for the banner and grab the guard from behind. Within seconds, the guard turned around and whacked him in the face with an open hand as a scrum of reporters snapped photos.
Galicia stumbled as another guard tried to restrain him, appearing to briefly put him in a stranglehold.
Galicia fought back, grabbing at the second guard's arms before the two yelled at each other outside Trump Tower.
A source familiar with the Trump campaign identified the first guard as Keith Schiller, Trump's director of security and longtime bodyguard.
After the 10-second tussle, Galicia told reporters the guards are "just acting like their boss. This man thinks he can do whatever he wants in this country, and we're going to stop him," Galicia said in Spanish.
An attorney for Galicia said he is exploring all "legal remedies that may be available" as Schiller appeared to "attempt to suppress free speech and the growing public criticism of the Trump campaign."
"The video in a sense speaks for itself," Benjamin Dictor told the Daily News Friday. "The actions were just exceedingly aggressive especially given the fact that demonstrators were on a public sidewalk speaking out about issues of public concern."
