WASHINGTON — The White House withdrew President Donald Trump’s nomination of Lance Schroyer to lead U.S. Immigration and Customs Enforcement on Thursday, extending the agency’s long-running stretch without a Senate-confirmed director. Schroyer, a former Oklahoma state trooper with limited immigration experience, was nominated in June. He is viewed as close to Homeland Security Secretary Markwayne Mullin, a former Oklahoma senator who took over the department in March. The White House gave no reason for withdrawing the nomination and did not say when it would name a replacement. The withdrawal came as ICE faces growing scrutiny over its expanded enforcement campaign and its rapid hiring of thousands of officers to carry out Trump’s mass-deportation promises. The agency’s arrests reached nearly 51,000 in August, the highest monthly total of Trump’s second term. ICE officers have also shot and killed several people, including two U.S. citizens in Minneapolis earlier this year, according to the report. Questions about those deaths helped stall Schroyer’s nomination in the Senate. Sen. Rand Paul, a Republican from Kentucky and chair of the Senate Homeland Security and Governmental Affairs Committee, said he had declined to schedule a hearing until the Department of Homeland Security provided information about civilian deaths during ICE operations. “I don’t have a concern with who the nominee was. I had asked them to give me an update on the internal investigation into civilian deaths,” Paul said. “And I’m still waiting.” Paul said he had planned to hold a hearing but learned that the nomination had been withdrawn only after the White House announced it publicly. Mullin had pledged a less conspicuous approach to immigration enforcement after taking charge of DHS, including a retreat from the highly visible operations in major cities that had prompted widespread condemnation. Enforcement has continued to accelerate despite that promise. ICE has not had a Senate-confirmed director since the Obama administration. David Venturella, a former executive with a private prison company, returned as acting director earlier this year after Todd Lyons resigned. When Trump announced Schroyer as his choice, he described him on Truth Social as a “PATRIOT with real operational experience” and a leader with “DECADES of experience locking up the worst of the worst.” The administration has not announced its next nominee.
