Thousands of anti-Trump protesters lit bonfires, burned ‘Make America Great Again’ hats, waved signs, and denounced the president while he held a rally next door inside the Target Center in Minneapolis.

Police used pepper stay as a small number of Trump supporters and anti-Trump protesters got into skirmishes.

Witnesses on the ground described a tense scene, with some anti-Trump protesters calling police pigs.

A number of officers in riot gear stood in a row just a few feet away, squaring off against protesters holding signs.
