President Trump has tried several different ways to stem the flow of migrants seeking asylum in the U.S., including requiring they first apply in any country through which they pass, as well as claiming to issue final rules that make it legal to detain children with their guardians.
While all of his programs have been challenged in court, on the whole the seem to be having the desired effect.
The Trump administration on Tuesday said arrests at the U.S.-Mexico border fell in September for the fourth month in the row, and credited cooperation from Mexico and Central American countries in cracking down on migrants.
But even with the falling number of arrests, there were still nearly one million migrants deemed inadmissible from October 1, 2018 through September 30, 2019, according to Mark Morgan, acting commissioner of the U.S. Customs and Border Patrol.
Morgan said there were just over 52,000 migrants either apprehended or encountered at the southwest border in September, down almost 65% from a peak in May of 144,000. That monthly total is still the highest September level since at least 2014, according to CBP statistics
One Trump policy, the Migrant Protection Protocols, has been allowed to move forward temporarily by the 9th U.S. Circuit Court of Appeals. It has pushed more than 51,000 migrants back to Mexico since January to await their U.S. asylum hearings.
The Trump administration has pushed Guatemala, Honduras and El Salvador to sign deals to accept more asylum seekers closer to home.
