The Proud Boys are celebrating their role in the US Capitol insu

The group - a Southern Poverty Law Center designated hate group that was told to "stand back and stand by" by Donald Trump during a presidential debate earlier this year - posted messages boasting and taking credit for the riot.

"For several hours, our collective strength had politicians in Washington in absolute terror. The treacherous pawns (cops) were also terrified," a Proud Boy wrote on the group's Telegram social media page.
