Todd Lyons, the acting director of U.S. Immigration and Customs Enforcement, has submitted his resignation and will step down from the role at the end of May, multiple outlets across the political spectrum confirmed Thursday. Lyons submitted his resignation letter to Department of Homeland Security Secretary Markwayne Mullin.

Lyons has served as acting director during a period of intensified immigration enforcement, overseeing large-scale deportation operations that have been a centerpiece of the Trump administration's immigration agenda. His tenure at ICE placed him at the forefront of some of the most high-profile and legally contested enforcement actions of the current administration.

No successor has been publicly announced. The departure creates a leadership vacancy at an agency that has seen significant operational expansion and public scrutiny over the past several months. DHS has not provided detailed comment on the circumstances surrounding Lyons' decision to resign or on plans for a permanent director.

The resignation comes as ICE continues to face legal challenges and congressional attention over its enforcement methods, detention conditions, and deportation procedures. Advocacy groups and lawmakers on both sides have weighed in on the agency's direction, though from sharply different perspectives regarding whether enforcement has been too aggressive or not aggressive enough.
