Up first, migrants from Central America are rushing to the U.S. illegally not because of violence or natural disasters in their home countries but because of jobs, a major new study found, challenging claims that they are asylum-seekers fleeing persecution. As Stephen Dinan reports, climate and the environment — a major explanation VP Harris has cited — was a reason for 3% of migrants. In other immigration news, a 17-day-old infant perished at the border after his mother carried him across the Rio Grande as part of a group of illegal immigrants, Homeland Security said this week. These stories are awful, and the responsibility rests on very many people, including the mother, the smugglers, the policy-makers and many others.
