A fight broke out at a US polling station after a man was told to take off his "Let's Go Brandon" hat before voting."

Footage shows a man arguing with poll workers at a voting center in Orangeburg, South Carolina, on Wednesday (Oct 30) after they insisted he removes his cap.

The man attempted to cast his vote while wearing a cap reading "Let's Go Brandon", a phrase which has become conservative code for "F**k Joe Biden."

A staff member informed him that state law forbids political attire inside voting centers.

And after a heated exchange, the man removed his cap and threw it to the ground.

The situation further escalated when he pointed at a female poll worker, who then hit him.

Workers tried to separate the two as the altercation continued, with one worker repeatedly calling for him to be taken outside.

South Carolina law requires a politically neutral zone within 500ft of polling places.

The South Carolina Law Enforcement Division has since launched an investigation into the incident, but details remain limited.
