U.S. President Donald Trump announced he would deploy federal forces to Portland, Oregon, citing the need to protect immigration and customs facilities from what he described as “Antifa and domestic terrorist attacks.”

Trump said the forces would have full authority to use force if necessary.

The move sparked wide controversy, echoing similar actions during his administration to deploy federal forces in other U.S. cities.

The White House has not provided further details on the timing or scope of the deployment.
