U.S. Customs and Border Protection is outlining southern border wall construction and improvements that are already underway. "Groundbreaking is scheduled for early April", Vitiello told reporters on Friday.
Speaking in OH earlier this week, President Trump boasted that building a new wall between the United States and Mexico was underway.
Trump tweeted that he had a "great briefing" on Wednesday about "the start of our Southern Border WALL!" with pictures of a wall being built.
In New Mexico, the Border Patrol will replace 20 miles of barriers that are meant to stop vehicles with new fencing to prevent people from crossing into the United States.
Instead, the project the president tweeted pictures of is replacement work on an existing two-mile barrier along the border - part of a project begun back in 2009.
Ms. White's comments came days after recent reports claimed Mr. Trump was considering shifting an unknown portion of Defense Department funds, set aside for department operations in the recently approved Omnibus spending package, toward the border wall effort.
The commander in chief eventually did sign the massive spending measure into law earlier this month, but not before taking to the airwaves to vent his frustration over the lack of financial support for the administration's immigration and border security agenda.
She was asked if paying $25 billion for the wall might hurt Mattis' key priority of rebuilding the military.
14 miles of "old, dilapidated landing mats" with a "steel bollard wall" in San Diego, where 14 other miles will be replaced.
The US CBP deputy commissioner also revealed that the new structures will be a "comprehensive solution that provides wall, lighting, enforcement cameras and other related technology, and all-weather roads to impede and deny illegal cross-border activity".
Trump made construction of a border wall a centerpiece of his presidential campaign.
