An executive order signed Monday by US President Donald Trump may permit “random fascist vigilantes” to help him crack down on protests across the country, according to one prominent civil rights lawyer.

The new order, which comes amid wider concern about Trump’s militarized takeover of Washington, DC, directs Secretary of Defense Pete Hegseth to ensure that each state’s National Guard is equipped to “assist Federal, State, and local law enforcement in quelling civil disturbances and ensuring the public safety.”

To that end, it orders the secretary to create a “standing National Guard quick reaction force” that “can be deployed whenever the circumstances necessitate,” not just in the nation’s capital but in “other cities where public safety and order has been lost.”

Monday’s order calls for the creation of “an online portal for Americans with law enforcement or other relevant backgrounds and experience.” Agency heads then “shall each deputize the members of this unit to enforce federal law.”
