Outdoor clothing retailer Patagonia plans to sue the Trump administration in response to the president's announcement Monday that he would dramatically reduce the size of two national monuments in Utah.

"Americans have overwhelmingly spoken out against the Trump Administration's unprecedented attempt to shut down our national monuments," said Patagonia CEO Rose Marcario in a statement. "We've fought to protect these places since we were founded and now we'll continue that fight in the courts."

The company also posted a message on its homepage that was highly critical of President Trump's decision to cut the size of the monuments.

"The president stole your land," the message declared in large type across the screen.

"In an illegal move, the president just reduced the size of Bears Ears and Grand Staircase-Escalante National Monuments," read a message in small font. "This is the largest elimination of protected land in American history."
