Yes, and one of the people who stormed the Capitol was a known BLM activist [0]. Doesn’t mean the overwhelming majority of people who stormed the Capitol weren’t Trump supporters.
The pro-Trump people saying “antifa stormed the Capitol!” are less surprising to hear when you recall the those who this summer said, “protest violence is the work of far-right agitators!” Arrest records and livestream footage prove both groups wrong in the vast majority of cases.
