Trump cuts size of protected monuments in Utah
Trump's move to reduce the size of the Bear Ears and Grand Staircase-Escalante national monuments is likely to be challenged in court.
Environmentalists in the US have filed a lawsuit against President Donald Trump - over the dramatic reduction of two historic national monuments in Utah.
The decision will see the Bears Ears National Monument shrink by nearly 90 percent and the Grand Staircase-Escalante by half.
The move could open up public lands across the US to mining and development, but opponents say it threatens archaeological sites and national heritage.
