In small section of border wall, Trump's promise takes shape

A government contractor, surrounded by existing Normandy barriers that separate Mexico and the United States, pours a concrete footer in preparation for a section of Pentagon-funded border wall along the Colorado River, Tuesday, Sept. 10, 2019 in Yuma, Ariz. A 30-foot high wall will replace the current five-mile section of border comprised of Normandy barriers and post-n-beam fencing. Construction began as federal officials revealed a list of Defense Department projects to be cut to pay for President Donald Trump's wall.
