FBI defends "measured" response to occupation of Oregon wildlife refuge

On Wednesday, Brown said “federal authorities must move quickly to end the occupation and hold all of the wrongdoers accountable,” Brown said.

Meanwhile, the Federal Fish and Wildlife Service said a new road reportedly built by the group may have damaged archaeological sites important to the Burns Paiute Tribe. Oregon Public Broadcasting reported that a new road was built, but a member of the group claimed they only removed snow from a path.

“There are any range of cultural artifacts that might have been impacted by this illegal construction,” service spokesperson Miel Corbett said.

The federal agency has not been able to access the refuge to confirm that a road had been built, or whether any artifacts were damaged, Corbett said.
