Secretary of State Marco Rubio did not mince words during an international gathering on political terrorism, calling the rise of leftist extremism a “new wave” of an “old evil.”

Speaking at the State Department’s Ministerial on the Resurgence of Political Terrorism on Thursday, the secretary addressed officials and experts from 67 countries on the threat of antifa and similar organizations around the world that perpetuate ideological violence and “work alongside hostile foreign states.”
