U.S. Sen. Maria Cantwell says she’ll support a bill to block a permit for the proposed Pebble Mine in southwest Alaska, according to APN. Cantwell’s announcement Tuesday is more fallout from the undercover operation an environmental group ran that targeted Pebble executives.

Pebble CEO Tom Collier resigned last week after the group released tapes of Collier and the CEO of Pebble’s parent company bragging about their political pull to men they thought were investors.

The executives also spoke of the mine as a 200-year project. Pebble’s permit application is for 20 years. Cantwell wants the Justice Department to investigate whether Collier committed perjury when he told a House committee last year that “Pebble has no current plans, in this application or in any other way, for expansion.”
