The president signed an executive order at the Interior Dept. with Vice President Pence, Interior Secretary Ryan Zinke and several lawmakers and governors. The order directs Interior to review larger national monuments created since 1996.
Trump said the Antiquities Act "does not give the federal government unlimited power to lock up" millions of acres of land and water. He especially criticized the Obama administration for an "egregious use of power" and an "abuse of the monuments designation," and said that it's time to end the abusive practice.
"It's gotten worse and worse and worse. This should never have happened," he said. "Now we're going to free it up."
"We're returning power back to the people," Mr. Trump said. "Today we're putting the states back in charge."
Pence called the use of the monuments designation "one of the great federal overreaches in recent decades."
Mr. Zinke said "somewhere along the line, the act has become a tool of political advocacy." He said the order "does not remove any monuments" or weaken any environmental protections.
The signing took place in a room at Interior with a framed portrait of Teddy Roosevelt, a bust of TR and mounted heads of a buffalo and deer on the wall. Among those in attendance were Sens. Mike Lee and Orrin Hatch of Utah and Lisa Murkowski of Alaska. Also Govs. Herbert of Utah and LePage of Maine.
