A legal environmental group is suing the U.S. government after the Trump administration announced plans to auction off massive sections of water surrounding American Samoa for potential deep-sea mining.

A legal environmental group sued the U.S. government on Tuesday to halt the Trump administration’s plans announced last month to auction off massive sections of water surrounding American Samoa for potential deep-sea mining.

Earthjustice filed the federal 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.
