Which is why we need to TOTALLY close the Southern Border...nobody going either by foot, car or plane...N or S. And quarantine everyone up to 100 miles N of the Mexican border. We are importing new cases.
Trump is building 1 mile of wall per day. Because there was virtually no wall before, he has started in the high traffic spots around towns and cities, and now he is moving to the lower traffic spots. The border is just shy of 2000 miles. He has a new wall over 200 miles now, mostly replacing useless border barriers. He has also put up roads and camera towers that track cross border traffic and allow the ICE to get quickly to the border for apprehension. At the moment they are able to just send people back because of the virus. Traffic is much lower this year because of the virus. And because the wall makes the crossing more difficult. Its still very possible just more difficult.
