The Trump administration fired four top officials at the Justice Department’s Executive Office of Immigration Review, which oversees U.S. immigration courts, late Monday. The officials were the chief immigration judge, Sheila McNulty; the acting director of the Executive Office of Immigration Review, Mary Cheng; the office’s general counsel, Jill Anderson; and its head of policy, Lauren Alder Reid. All were civil servants, not political appointees. Alder Reid said they were not given any warning. “My career Senior Executive Service colleagues and I are shocked and severely disappointed in the decision to remove us from our positions without notice or cause,” she said. “We have dedicated our careers to upholding the rule of law, regardless of the administration. Our continued pursuit of justice will not be diminished.” Donald Trump 7 hours ago Trump highlights partnership investing $500 billion in AI Trump administration 4 hours ago Senators receive affidavit containing new allegations against Pete Hegseth, who denies the claims The four fired officials had decades of experience leading the nation’s overburdened immigration courts.
