FLAGSTAFF, Ariz. (AP) -- A mining industry group is asking the U.S. Supreme Court to review an Obama-era ban on new mining claims around the Grand Canyon.
The petition filed Friday by the American Exploration and Mining Association comes as President Donald Trump's administration reviews a portion of the ban.
The Interior Department implemented the ban in 2012 amid concern about possible water contamination.
A federal law gives the Interior secretary authority to withdraw land from mining claims for up to 20 years without congressional approval.
A provision allowing a legislative veto has been deemed unconstitutional.
