Thousands of supporters and protestors showed up for the Donald Trump rally at the Tucson Convention Center on Saturday afternoon.

However, one of those protesters received an unexpected blow from a Trump supporter while attending the rally.

In the video, Trump is overheard talking about two protesters, one man dressed in an American flag shirt holding up a white sign and a woman who was wearing what appears to be a Ku Klux Klan face mask, who were walked out of the rally.

Trump says, "There's a disgusting guy...he's a disgusting guy...really disgusting." In the video, it appears Trump is making those comments towards the woman who was wearing the KKK outfit.

As the duo walks away and up the stairs, a man who was in the stands grabs the protester wearing the American flag shirt and punches him in the face. The protester falls to the ground and the man continues to punch and kick him several times.

The Trump supporter is then led out of the venue in handcuffs by police.

The man who was assaulted gets up and walks away behind police while holding up two peace signs.

Tucson police arrested the man who attacked the protester. He has been identified as 32-year-old Tony Pettway, charged with assault with injury.
