Outdoor recreation company Patagonia sued Wednesday to block President Trump from shrinking Bears Ears National Monument in Utah.

Patagonia called Trump’s decision to downsize the Bears Ears monument by 85 percent an “extreme overreach in authority.”

Under the proclamations signed by Trump on Monday, protected territory in Bears Ears and the Grand Staircase-Escalante national monuments in Utah will be reduced by nearly 2 million acres in total.

Counting Patagonia's lawsuit, the Trump administration has been hit with four legal challenges, the Associated Press reported.

“We've fought to protect these places since we were founded and now we'll continue that fight in the courts," Patagonia CEO Rose Marcario said in a statement earlier in the week.

Patagonia had warned it would sue the Trump administration due to the announcement and had replaced its standard homepage with a black slate that reads: "The President Stole Your Land."

"In an illegal move, the president just reduced the size of Bears Ears and Grand Staircase-Escalante National Monuments," Patagonia's website also says in smaller font. "This is the largest elimination of protected land in American history."

Interior Secretary Ryan Zinke responded, saying it was "shameful" that Patagonia would "blatantly lie."
