UPDATE 12:16 p.m. EST:
Trump is also expected to sign executive orders related to offshore drilling and veterans' affairs.
The America First Energy Executive Order will call for a review of rules on offshore oil and gas drilling, ABC News reports. The veterans' affairs order will create an "office of accountability and whistleblower protection" in the Department of Veterans' Affairs. A third order will call for a task force to "examine the concerns of rural America" and suggest laws to help them.
This will bring Trump's exeuctive order count to 32 in his first 100 days, which the White House says is the highest number of any president since World War II.
ORIGINAL STORY: Near the end of his term, former President Obama designated multiple areas national monuments, earning praise from conservationists but criticism from those who called it government overreach.
An executive order to be signed Wednesday by President Trump may undo those designations, The Hill reports. It will instruct Interior Secretary Ryan Zinke to review whether or not monuments designated in the last 21 years were within the scope of the a law that lets the president designate federal land as monuments without congressional approval.
The order specifically targets Bears Ears National Monument, designated as such by Obama in December, the Salt Lake Tribune reports. Many Utah officials argue the size of the monument should be scaled back.
