Vos, who is the longest-serving Assembly speaker in Wisconsin history, is under fire from supporters of former President Donald Trump for his refusal to impeach the official overseeing the state's elections.

The bipartisan Wisconsin Elections Commission now has until June 28 to assess whether the recalled signatures meet the requirements to trigger a recall election. The initial attempt at recall was rejected by the commission for insufficient valid signatures.

Former Wisconsin Supreme Court Justice Michael Gableman, aligning with Trump supporters, submitted over 9,000 signatures on May 28 in an effort to recall Vos. However, Vos claims to have found thousands of invalid signatures, including 2,000 collected from outside his current legislative district, over 400 instances of multiple signatures from the same individuals, and nearly 350 signatures collected beyond the permitted time window.

Vos further alleged that signatures were obtained from non-existent addresses, vacant properties, and non-residential locations. In response, the committee responsible for circulating the recall petitions branded Vos' challenge as "laughable," standing by the sufficiency of their collected signatures.

To successfully trigger a recall election in Vos' district, 6,850 valid signatures are required. In their initial submission in March, the committee had submitted over 9,000 signatures, with the elections commission validating only 5,905 of them as legitimate.

Vos's refusal to acquiesce to calls for the decertification of President Joe Biden's narrow victory in Wisconsin's 2020 election further fueled the ire of Trump loyalists. Despite enduring two partial recounts, multiple lawsuits, an independent audit, and a review by a conservative law firm, Biden's win by approximately 21,000 votes has remained intact.

Adding to their discontent, Vos did not support a plan to impeach Meagan Wolfe, the state's top elections official. The complexities of the recall process are exacerbated by the implementation of new legislative maps scheduled to take effect in the upcoming fall election. Seeking clarity, the elections commission has sought guidance from the Wisconsin Supreme Court on whether a recall election should occur within Vos' existing district or under the new boundary lines set for the regular November election.
