 Donald Trump entered the Oval Office with a campaign promise to build 450 miles of a new “border wall system” – a combination of infrastructure including bollard barriers, roads, perimeter lighting, enforcement cameras and other technology – even amid the pandemic, has continued at an increasing pace. According to Customs and Border Protection, 400 miles of the border wall system has been completed so far, with physical barriers from 18-30ft tall. If he wins, he may well aspire to wall off the border in its entirety.
