A federal judge in Austin, Texas has ordered the state to remove a large floating barrier from the middle of the Rio Grande River, following protests from the U.S. and Mexican governments. The U.S. government argued that the buoys violated the federal government's exclusive authority to regulate navigable waters, and Judge Ezra found that the buoys interfered with the federal government's ability to manage the river and caused environmental damage. The ruling is the latest development in the Biden administration's efforts to address the ongoing migrant crisis at the U.S.-Mexico border.
