arrested

, and the 200-year-old cottonwood was bulldozed.

In the 48 hours since the early morning raid, land defenders have refused to leave and remain in an ongoing standoff with federal agents. Numerous participants told The Intercept that around 50 people are holding the line against further construction, with dozens more en route following urgent calls to support the encampment and defend the
