After speaking with other witnesses, he said that the man was walking toward an area where a group of Trump supporters were gathered and started throwing colorful pieces of paper in the air which grabbed attention from onlookers. After tossing the papers, the man then doused himself with a flammable liquid, presumably gasoline, and lit himself on fire.

This sounds too gay to be a Trump supporter, throwing colourful paper to get attention before setting yourself on fire?

I'm more worried about a guy suddenly going dark and missing fertiliser with heavy machinery if it was someone on the right.
