U.S. border sees under 100K migrants for first time in 5 months

News of the decline comes as 22 people were killed and dozens others were injured in a mass shooting in El Paso – a border city that has become the face of the migration crisis. The shooting suspect is believed to have posted a racist, anti-immigrant screed on the internet before the attack.WATCH: Families enjoy ‘teetertotter wall’ on both sides of U.S.-Mexico border Trump visited both El Paso and Dayton, Ohio, the scene of a second mass shooting last weekend where 9 died and dozens were injured. He was greeted by protests in both places. Critics contend Trump’s own words have contributed to a combustible climate that has spawned death and violence.Over the past few months, there has been outcry over squalid conditions for migrant children crammed into border facilities not meant to hold them longer than 72 hours. Some were kept for weeks because of delays in handling such cases.Acting Homeland Security Secretary Kevin McAleenan traveled to another border town – Yuma, Arizona – on Thursday to detail the border numbers. He said that in mid-June there were more than 1,250 children in custody for 72 hours or longer — but that had dropped to about 160 children by Wednesday, with an average custody time of fewer than 24 hours.There had been about 10,000 families in custody; now there are 2,000 and they are held about 34 hours, he said. Single adults are down from 8,000 to about 2,000 in custody. He did not provide the length of detention for single adults, who are often held the longest.Seasonal declines in migration are common; fewer people make the dangerous journey when it’s so hot. But McAleenan said the May-to-July drop was much steeper than the same time last year.He stressed it did not mean the crisis had ended.“The situation is improving by every available metric, but, and I want to be very clear about this, we remain at and beyond crisis levels,” McAleenan said.WATCH: U.S. Supreme Court lets Trump use military funds for border wall Guatemalan officials recently agreed to what’s known as a “safe third country” pact with the U.S., meaning anyone coming through that country from El Salvador or Honduras would not be able to claim asylum in the U.S. The agreement was made even as Guatemalan courts blocked the effort. U.S. officials believe it will be in effect by the end of the month.The Trump administration also sought to effectively end asylum protections at the southern border, though that effort was blocked temporarily by U.S. courts.In June, after Trump threatened tariffs on Mexico, leaders there agreed to expand the administration’s program forcing U.S. asylum seekers to wait on the Mexican side of the border. Mexican police, soldiers and National Guard forces are raiding hotels, buses and trains to round up Central American migrants before they can make it to the border. And they are busing migrants from the Texas border hundreds of miles to inland towns.While July’s border numbers are below the peak of earlier this year, they are still high compared to recent history. Until this March, July’s total would have been the highest number in at least the last six years, spanning multiple previous surges of adults and children crossing to the U.S.
