( CNN) A distinguished federal magistrate who most Americans simply know of as the specific objectives of Donald Trump’s bigotry when he was still a candidate for chairperson has returned to the public spotlight — and not by choice.

Judge Gonzalo Curiel, a magistrate in the southern district of California, has been assigned to hear the case of a Deferred Action for Childhood Arrivals( DACA) recipient who alleges that he was improperly deported by immigration authorities.

Juan Manuel Montes, 23, says that he was picked up and deported to Mexico in February, a claim that the Department of Homeland Security disagreements. When Montes tried to reenter the US two days later, he was arrested by Border Patrol agents. DHS says he voided his DACA status by leaving the country; he tells the leaving was involuntary.
