House Natural Resources Committee Chairman Rob Bishop has invited the founder and owner of outdoor clothing retailer Patagonia to testify before his panel to talk about the company’s opposition to President Trump’s rollback of two national monuments in Utah.

Patagonia sued the Trump administration this month for shrinking the size of the Bears Ears and Grand Staircase-Escalante national monuments, and the company’s owner, Yvon Chouinard, has publicly feuded with the president and the Utah Republican’s committee.
