Trump on Wednesday warned members of the anti-fa movement that opposition to them could be "tougher" and "much more violent" if their critics decide to "mobilize."
"They better hope that the opposition to antifa decides not to mobilize,” Trump told the conservative The Daily Caller in an interview. "Because if they do, they’re much tougher. Much stronger. Potentially much more violent."
Antifa groups describe the use of violence as necessary to combat authoritarianism. They have participated in brawls with right-wing groups across the country, including the white nationalist demonstrators during the Charlottesville, Va. rally last year.
The Anti-Defamation League describes the antifa ideology as "rooted in the assumption that the Nazi party would never have been able to come to power in Germany if people had more aggressively fought them in the streets in the 20s and 30s."
