Well-regulated immigration in which EACH immigrant is screened for terrorist and criminal activities is needed prior to admission. Further, Mexico should bear the housing and cost for all asylum seekers before they can be processed in the United States. It would be interesting to note how quickly these greatly inflated numbers would decline. 

Mexican President Obrador is pretending to be dealing with the Trump administration in the middle of the threat to impose tariffs on all Mexican exports to America of 5% and increasing after that if Mexico continues to facilitate the entry of unsavory characters to the United States. What the mainstream media (MSM) will never tell the public is that a significant number of terrorists, criminals with felonies, drug dealers, child sex traffickers, gun runners, assassins  and paramilitary as well as military troops are crossing our Southern border in great numbers right along with legitimate people who are seeking the relative safety that crossing the border offers some immigrants. However, as we know and has been documented by the federal government, 90% of all asylum seeker claims are completely false. These people are distributed around the country while they await trial and the vast majority of them never show up of trial and future disposition. The whole illegal immigration system is the largest national security threat faced by the innocent people inside the United States. You and your neighbors have done nothing to deserve what is happening and what is going to happen.
