The Republican governor withdrew his new rules requiring all commercial trucks from Mexico to undergo additional controls to curb the flow of immigrants and drugs, and sparked a dispute with the Biden government over immigration policy. Some truckers said they waited more than 30 hours to pass. Others blocked one of the busiest shopping bridges in the world in protest. Abbott, who will be re-elected in November and has made borders his top priority, has lifted all inspections after reaching agreements with neighboring Mexican states that he says outline new border security commitments. The latter was signed with the governor of Tamaulipa, who earlier this week said the inspections were too zealous and wreaked havoc. On Friday, he joined Abbott and said they were ready to work together. When Abbott first ordered the inspections, he did not say that their lifting depended on such arrangements with Mexico. The pressure on Abbott to step down escalated as the border impasse worsened. The American Trucking Association described the inspections as “completely flawed, unnecessary and add significant weight to an already strained supply chain.” A Mexican customs service estimated the losses at millions of dollars a day and product distributors warned of empty shelves and higher prices if the order was not canceled soon. Abbot acknowledged the trade slowdown, but showed no signs of regretting it. He said he was ready to resume inspections if Mexican states did not suspend the deal. “I do not hesitate to do it at all,” Abbott said. The U.S.-Mexico border is vital to the U.S. economy, and most of it is located in Texas – about 1,200 miles (1,931 kilometers) – of any other state. The United States imported $ 390.7 billion worth of goods from Mexico last year, second only to China. The trucks are inspected by US Customs and Border Protection agents upon entering the country. Texas began its own inspections after the Biden administration said pandemic-related restrictions on asylum at the border would be lifted May 23. Abbott called the inspections a “zero tolerance policy for unsafe vehicles” smuggled by migrants. He said Texas would take many steps in response to ending asylum restrictions, which is expected to lead to an increase in immigrants coming to the border. State troops inspected more than 6,000 commercial vehicles last week, according to the Texas Department of Public Safety. Nearly 1 in 4 trucks were pulled off the road for serious offenses involving defective tires and brakes. The soldiers did not detect any human or drug trafficking during the inspections, said Public Security Director Steve McCrow. He described it as a surprise, saying the cartels knew the inspections were taking place. But migrants stop at ports of entry only in about 5% of CBP encounters. The vast majority cross in mountains, deserts and cities between the official crossroads. The dynamics of drug seizures are different, as fentanyl, heroin, methamphetamine and other hard drugs were seized in the vast majority of official crossings instead of each other. Their compact size and lack of odor make them extremely difficult to detect. Abbott has also chartered buses to Washington, DC, for immigrants who wanted to go. The first miscarriages took place on Wednesday, prompting criticism from the Biden government. On Thursday, CBP commissioner Chris Magnus said Texas was moving migrants without “adequate coordination” with the federal government.
