President Barack Obama on Monday will announce five new national monuments that will be added to the U.S. list of protected land.
In a rare invocation of his executive powers, Obama will designate the First State National Monument in Delaware. He also is expected to designate a site on Maryland's Eastern Shore as a national monument to commemorate famed abolitionist Harriet Tubman and the Underground Railroad, a White House official said.
The three other sites Obama will name are the Rio Grande del Norte National Monument in New Mexico, the Charles Young Buffalo Soldiers National Monument in Ohio and the San Juan Islands National Monument in Washington state.
