U.S. senators from New Mexico, Colorado, Washington state, Nevada and Hawaii released statements denouncing the Trump administration’s nascent approach to public-lands management.

“Erasing America’s national monuments from the map would devastate our thriving outdoor recreation economy, which generates 68,000 jobs and $6.1 billion of annual economic activity in New Mexico alone,” said New Mexico Sen. Martin Heinrich. “And it could easily lead us down a slippery slope toward the selloff of our public lands to the highest bidder and massive giveaways of public resources to special interests.”
