PHOENIX — Three Republican congressmen have signed a letter asking the Trump administration to eliminate four Arizona national monuments.

The letter signed by Rep. Trent Franks, Rep. Andy Biggs and Rep. Paul Gosar targets the Grand Canyon-Parashant, Ironwood Forest, Sonoran Desert and Vermilion Cliffs national monuments, the Arizona Republic reports. It was sent to Secretary of the Interior Ryan Zinke June 30.

Former President Bill Clinton created the four national monuments under the 1906 Antiquities Act. The letter states that the act later became a "tyrannical tool that presidents have manipulated to exercise unfettered land grabs to the detriment of state and local interests."

It also claims that the monuments have disrupted collaborative fish and wildlife management, prevented multiple-use on State Trust lands and puts national security at risk.

Conversation groups say the monuments should be permanently protected to preserve their beauty and wildlife.
