'Don't come over': Biden tries to clean up mixed border message Print this article President Biden is trying to right the White House's scrambled message to migrants seeking to cross the United States-Mexico border. Biden implored migrants not to travel north as his new administration struggles to manage the influx at the southern border, particularly of unaccompanied minors. The Federal Emergency Management Agency, for instance, has helped to turn the Dallas Convention Center into an immigration facility that can house up to 3,000 migrant teenagers. "Yes, I can say quite clearly: Don't come over… Don't leave your town or city or community," Biden told ABC News in an interview aired Tuesday.
