Ghost of Andrew Eaton said:
This may have already been answered but can the President actually do this?
ANTIFA is a scourge on our country and should be defeated.
DOJ can label a group as domestic terrorists so Trump's orders is likely to DOJ to do it.
The Earth Liberation Front and the Animal Liberation Front are two previous examples. They operated very much like antifa, in their own cells without a centralized control structure. For many years, they were considered by the FBI to be the most dangerous domestic terrorist groups in the US.
"If you will not fight for right when you can easily win without blood shed; if you will not fight when your victory is sure and not too costly; you may come to the moment when you will have to fight with all the odds against you and only a precarious chance of survival. There may even be a worse case. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves." - Sir Winston Churchill
