AUSTIN, Texas (AP) — The deadliest smuggling attempt in U.S. history underscores the limitations of Texas Gov. Greg Abbott’s massive border security operation. Texas is spending $3 billion on a mission that includes National Guard members, jail for suspects arrested on trespassing charges and buses to shuttle migrants to Washington, D.C. But the number of people found illegally crossing the nation’s entire southern border is around its highest in two decades. Abbott has pointed the finger at the Biden administration. This week, Abbott said Texas state troopers would begin additional inspections of tractor-trailers. State authorities haven't said how many trucks are being stopped.
