Washington Attorney General Bob Ferguson spearheads an 11-state coalition joining the fight to overturn President Donald Trump’s downsizing of two national monuments in Utah, a court battle that the American Farm Bureau Federation says will affect the value of federal rangelands and private ranches in the West. Ferguson’s office submitted two identical briefs Monday to the federal district court in Washington, D.C., siding with tribes and environmental groups suing Trump over the Bears Ears and Grand Staircase-Escalante national monuments.The briefs argue that the Antiquities Act of 1906 gives presidents power to create national monuments, but not to shrink them. “Simply put, the Act is a one-way ratchet in favor of preservation,” the brief states.The Trump administration last year roughly halved the 1.7 million-acre Grand Staircase-Escalante monument created by President Bill Clinton in 1996. It also reduced by about 85 percent the 1.35 million-acre Bears Ears monument designated by President Barack Obama in 2016.The Wilderness Society, the Natural Resources Defense Council, the Hopi Tribe and others are seeking to overturn the actions. Two cases are moving forward, one for each monument. The American Farm Bureau Federation is seeking a judge’s permission to intervene in both to support Trump’s action.
