The acting director of U.S. Immigration and Customs Enforcement, Todd Lyons, is set to leave his position later this spring after overseeing the agency during a major expansion under President Donald Trump’s immigration policies.

Department of Homeland Security Secretary Markwayne Mullin announced Thursday that Lyons will step down on May 31.

“Director Lyons has been a strong leader of ICE and played a key role in efforts to remove dangerous individuals from American communities,” Mullin said in a statement, crediting him with revitalizing the agency’s operations.

Mullin added that Lyons would be transitioning to an opportunity in the private sector.

During his tenure, Lyons oversaw a significant expansion of ICE, supported by funding from a sweeping tax and policy package backed by the administration. The agency increased enforcement operations nationwide, deploying officers to major cities including Chicago, Los Angeles, and Minneapolis.

The intensified efforts were part of a broader strategy to deliver on Trump’s campaign promises to strengthen immigration enforcement and enhance public safety.
