Drone captures migrants crossing the Rio Grande

STORY: The U.S. Justice Department is suing Texas over the barriers that are being put in place to block migrants crossing from Mexico, part of Texas Republican Governor Greg Abbott's initiative dubbed Operation Lone Star to deter migrants.

The number of migrants caught crossing the U.S.-Mexico border illegally has dropped since Biden implemented a restrictive new asylum policy in May. Even so, roughly 100,000 were apprehended in June.

In addition to the border barrier, Abbott's Operation Lone Star also has included the deployment of thousands of National Guard troops and a campaign to bus migrants to Democratic-led cities further north. And in recent months, National Guard troops have strung up razor wire to block migrants from crossing the Rio Grande.
