The presence of Antifi has been raised in association with the terrorist rioting. There can be no doubt that there are groups involved that are inciting the pliable masses.
The President has told us he is going to go get them. He named Antifa but indicated knowledge of others. His government has had some part of four years to infiltrate and learn about these instigators who incite the pitiful and pliable masses.
The question becomes who are Antifa and the others? I suspect the President has precise and plentiful knowledge. He not only knows who and where but has substantial evidence on the enabling funding
Now as he always says........ we’ll see
BTW, China has been funding Antifa and BLM for a while now. Trump knows.
