The Department of Homeland Security is making cuts to three key offices that oversee civil rights protections across its broad mission, suggesting that they were impeding immigration enforcement efforts.

President Donald Trump’s administration purged an office within the Department of Homeland Security on Friday that was tasked with limiting abuse by immigration officials. The department’s Office of Civil Rights and Civil Liberties was shut down—effectively immediately—at the same time the administration is under fire for deporting migrants to El Salvador before some could plead their case in an immigration court.
