Summary

Wisconsin Assembly Bill AB24 was vetoed by Governor Tony Evers on April 3, 2026. The bill would have created Wisconsin Statutes 59.28(3) and 79.039(1g), establishing a framework for county sheriffs to assist with certain federal immigration enforcement functions. Sponsored by 42 Republican legislators, the bill was subject to extensive Senate amendment activity before ultimately being vetoed, preserving the status quo for Wisconsin law enforcement cooperation with federal immigration authorities.

What changed

Wisconsin AB24, a bill that would have created new statutory provisions under Wis. Stat. 59.28(3) and 79.039(1g), has been vetoed by Governor Tony Evers on April 3, 2026. The legislation was sponsored by 42 Republican legislators and passed both chambers before being vetoed. The Senate considered multiple amendments from Democratic senators (Carpenter, Drake, Hesselbein, Johnson, Keyeski, Larson, Ratcliff, Roys, Spreitzer, Wall, Wirch, and others) addressing various aspects of sheriff cooperation with federal immigration functions, as well as a Senate Substitute Amendment offered by the minority caucus, all of which were either withdrawn or rejected. The bill's fiscal estimate (FE) indicated significant anticipated implementation costs.

Wisconsin county sheriffs and law enforcement agencies should note that no new statutory obligations regarding federal immigration cooperation have been established. The veto preserves existing Wisconsin law and discretion on immigration assistance matters. Government affairs and law enforcement compliance teams in Wisconsin should continue to monitor for potential legislative reintroduction or similar proposals in future sessions, as the underlying policy debate remains active given the substantial legislative support AB24 received.

What to do next

  1. Continue current policies on sheriff cooperation with federal immigration authorities as AB24 did not become law
  2. Monitor Wisconsin legislative activity for reintroduction of similar immigration assistance bills in future sessions
