August 20, 2026 — A legal environmental group sued the U.S. government on Tuesday to halt the Trump administration’s plans announced last month to auction off sections of water surrounding American Samoa for potential deep-sea mining.
Earthjustice filed the lawsuit against the U.S. National Marine Fisheries Service and U.S. Commerce Secretary Howard Lutnick on behalf of two groups: Fa‘asao Amerika Samoa and Conservation Council for Hawai‘i.
The legal nonprofit is requesting that a judge order the National Marine Fisheries Service to stop moving forward with its plans and to comply with the Endangered Species Act and other federal laws.
“The United States has never opened its waters to deep-sea mining. Until now,” the lawsuit stated.
It noted that the U.S. plans to sell leases with the intention of allowing mining across 33 million acres of seabed off American Samoa that is rich in minerals including nickel, cobalt and manganese that are used to build batteries, electronics and other products.
