ONLY due to a curfew and heavy police/NG presence. Congress got cucked, for the world to see. Those who considered themselves the masters of the people crumpled and hid like whipped bitches when the people came to call. Still don't know if even ONE "member of congress" volunteered to have some protesters in and speak their piece, or volunteered to speak to their fellow Americans. And for those in congress who are veterans and wouldn't engage with the people...just a bunch of pussies.
Another thought...does it really matter if the protesters were Antifa or not? The issue is that Americans, sick of what's happening in congress (deliberately not capitalized), finally decided to pay a call on them. Could some be Antifa? Maybe. But many more were not. As can be seen, congress knows now that an awful lot of Americans don't support them. No trust, no credibility.
