SHREVEPORT, La -- It was a "mistake." U.S. Sen. Bill Cassidy, R-La., says that's how the acting director of Immigrations and Customs Enforcement described the drop-off of two busloads of Haitian migrants a week ago at the Shreveport bus station, with no organization, following their release from Louisiana detention centers. "I can't help but think that the reason they have the problem is because they have an overflow of people in detainment. And they just have to do something with them. And so their normal operating procedure just got busted," Cassidy told KTBS 3 News. Cassidy says a record of more than a million migrants have illegally crossed the U.S. southern border this fiscal year, with three months still to go. So he fears last Friday's mass release won't be the last.
