A bill authored by State Sen. Eric Wimberger in the Wisconsin Senate seeks to ensure state and local government hires meet federal employment eligibility standards through mandatory use of E-Verify, according to the Wisconsin State Senate.

According to the Wisconsin State Legislature's official website, the bill was described as follows: "the employment eligibility verification program and granting rule-making authority. (FE)".

The following is our breakdown, based on the actual bill text, and may include interpretation to clarify its provisions.

In essence, this bill mandates that state agencies and local governmental units in Wisconsin verify the employment eligibility of their hires using the Federal Employment Eligibility Verification Program, known as E-Verify, effective from the bill's enactment date. It prohibits the state from purchasing materials or contracting services from employers not enrolled in E-Verify or those knowingly employing individuals ineligible to work in the U.S. Similarly, construction contracts above $50,000 must adhere to these verification requirements. Contracts must include a clause confirming the employer's compliance with E-Verify, and any non-compliant contracts will be terminated without liability for the state. The bill is void if the E-Verify Program is discontinued.

The bill was co-authored by Representative Jim Piwowarczyk (Republican-98th District), Senator Steve L. Nass (Republican-11th District), and Senator Cory Tomczyk (Republican-29th District). It was co-sponsored by Representative Lindee Rae Brill (Republican-27th District), Representative Robert Brooks (Republican-59th District), and Representative Barbara Dittrich (Republican-99th District), along with seven other co-sponsors.

Eric Wimberger has authored or co-authored another 39 bills since the beginning of the 2025 session, with none of them being enacted.

Wimberger graduated from St. Cloud State University in 2001 with a BS and again in 2005 from Marquette Law School with a JD.

Wimberger, a Republican, was elected to the Wisconsin State Senate in 2025 to represent the state's 2nd Senate district, replacing previous state senator Robert Cowles.

In Wisconsin, the legislative process starts when a senator, constituent, group, or agency proposes an idea for a bill. After drafting, the bill is introduced, numbered, and referred to a committee for review and public input. If approved, it moves through three readings and votes in both the Senate and Assembly. Once both chambers pass the same version, the bill goes to the governor, who can sign it, veto it, or let it become law without a signature. Only a small share of bills introduced each session ultimately become law. You can learn more about the Wisconsin legislative process here.
