A federal judge in California issued a preliminary injunction on Wednesday to temporarily block the Trump administration from terminating Temporary Protected Status (TPS) for hundreds of thousands of immigrants from from El Salvador, Haiti, Nicaragua and Sudan.

Why it matters: This is a significant victory for more than 300,000 TPS beneficiaries and advocates seeking to reinstate the program that protects some undocumented immigrants from deportation — many of whom have been living in the U.S. for decades and have children who are American. U.S. District Judge Edward Chen wrote that the government must maintain TPS while a suit challenging its decision plays out in court. Chen's ruling comes as recipients from Sudan were set to lose their protections next month.
