Department of Homeland Security officials are close to wrapping up the testing and evaluation phase for the eight border wall prototypes that were constructed in San Diego, Calif., two senior DHS officials confirmed Friday.

“The testing portion has been completed. Right now, the results of the information gathered in that test period are being looked at by engineers, Border Patrol, and many others, so we can look at what features of those designs are the best to do the job,” a Customs and Border Protection spokesman told the Washington Examiner.
