A Colorado schoolboy has been kicked out of class for having a Gadsden Flag patch on his backpack – despite the governor calling it a 'proud symbol of the American revolution'.

Footage shows Jaiden, 12, and his mother talking to an administrator from The Vanguard School who claimed that the flag had 'origins with slavery.'

The staffer claims that the patch was 'disruptive to the classroom environment,' as she claimed it has 'origins with slavery.'

He was told that the patch, which has 'Don't Tread on Me' emblazoned on it along with a rattlesnake, was against the district's policy and he was not allowed to go back to class without removing it. 

The pupil was told by the administrator: 'So the reason that they do not want the flag – the reason we do not want the flag displayed – is due to its origins with slavery, and the slave trade.
