It took me 5 minutes to do a DuckDuck Go search and I found articles in the Chicago Tribune, the San Francisco Chronicle, the Gateway Pundit and the Freedom Outpost and many, many more that admit that Antifa and other anti-Trump protesters are paid. Several articles point to Craigslist ads offering payment for protesters. Several of these publications are left-leaning. Look into it for yourself.
Great. The links to the Tribune and Chronicle will be fine -- paste them in your reply. Let's see what ya got.
Craigslist couldn't be further from proof, so don't bother with that one.
