Social media lit up on Saturday with videos from the pro-Trump and anti-Trump rallies in Washington, D.C.
The violence was caught on camera as supporters were trying to leave their respective rallies.
Caution, this video may disturb some viewers. Viewer discretion is advised.
The video shows a man trying to walk away when someone in the crowd hits him in the head. He then goes down to the ground, when other members of the anti-Trump crowd begin to kick him while he's down.
Scenes like those sparked a reaction from the President himself.
He called the group 'Antifa' "Radical Left ANTIFA SCUM" in his tweet. He took exception to the crowd hitting people on the way out of the rally.
"Radical Left ANTIFA SCUM was easily rebuffed today by the big D.C. MAGA Rally crowd, only to return at night, after 99% of the crowd had left, to assault elderly people and families. Police got there, but late. Mayor is not doing her job!," Trump tweeted.
