That confusion over who decides what is corrosive or disparaging is at the heart of a lawsuit recently filed by the Public Employees for Environmental Responsibility, or PEER.
After nine months of failed Freedom of Information Act requests to find out how those decisions were made, PEER sued the Interior Department.
“The public has a right to know who inside this administration is deciding what version of American history gets told at our national parks and other public lands, and on what basis,” Tony Irish, PEER’s senior council, said in a statement.
