A federal judge on Thursday expressed concern and skepticism over a controversial law that makes entering Texas illegally a state crime while hearing oral arguments over a motion for a preliminary injunction to block the law. The measure, SB4, which is set to go into effect on March 5, grants local and state law enforcement the power to arrest migrants and state judges the ability to issue orders to remove them to Mexico. The Department of Justice sued the state, arguing the federal government has exclusive authority to enforce immigration law. US District Judge David Ezra emphasized that he was sympathetic to the state’s concerns about the complicated situation at the border and the issues plaguing the country’s immigration system, making it clear that something must be done to improve the nation’s immigration laws. Ezra sharply questioned several provisions within the law and flat out rejected the state’s argument that an “invasion” was taking place at the Texas-Mexico border. Ezra said he would rule “as quickly as I possibly can,” assuring both parties he would give enough time for either side to file an appeal.
