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.

A spokeswoman for the department, Tricia McLaughlin, said in a statement Friday that it was implementing a “reduction in force” for three offices: the Office for Civil Rights and Civil Liberties, the Office of the Immigration Detention Ombudsman, and the Office of the Citizenship and Immigration Services Ombudsman.
