How has border security changed under President Trump's administration?

Under President Trump's administration, border crossings have seen a dramatic drop. Border Czar Tom Holman reports being happy with the results so far but emphasizes he is not yet satisfied with the overall progress. Holman states that his goal is to continue working until every gang member, illegal alien, public safety threat, and national security threat is eradicated from the country. While acknowledging positive developments in border security, he maintains that there is still significant work to be done to fully address the challenges at the border.
