The U.S. Justice Department has filed a motion in a federal court to order the state of Texas to remove a floating barrier covered in razor wire, which was installed by the state to deter migrants from crossing into the United States. The motion argues that the barrier poses a threat to navigation and public safety, and could potentially harm or kill migrants seeking asylum in the United States. The court is expected to make a decision soon on the Justice Department's request for a preliminary injunction to prevent "irreparable harm" to foreign relations, public safety and navigation.
