Interior Secretary Ryan Zinke on Thursday provided few details about his review of national monuments, but he expressed clearly his frustration with the process for how monuments are made.

In his executive summary of the review, in which he said he will recommend that President Trump shrink a “handful” of the 27 national monuments he reviewed, he strongly suggested he would seek to change, and limit, the 111-year-old law that gives presidents the power to designate national monuments on land already owned by the federal government.
