President Trump needs to condemn Antifa and BLM too.
Both groups should be labeled Terrorist by the justice department, the leaders should be arrested, seize their assets, interrogate them, and charge them with terrorism.
The catch is - investigating Antifa will be seen as Trump making political retaliation - he has to do it quietly like Obama did with IRS investigations and having the justice department put out studies about how leftist groups are a real threat to the country.
Investigating BLM will be seen as a racist attack.
There’s no political will to do either. I think Trump could generate that will but the GOP will turn against him and immediately impeach him.
