President Donald Trump's campaign filed a petition on Tuesday challenging Wisconsin's presidential vote results with the state's supreme court, the latest attempt to reverse the 3 November election won by Democratic Joe Biden.
The petition alleges that election officials were directed to fill in missing information on ballot envelopes, issued absentee ballots without receiving applications and allowed people to improperly claim a "confined" absentee voting status.
The petition, filed on behalf of Trump, his campaign and U.S. Vice President Mike Pence, also takes issue with voting events in city locations outside of polling stations, according to court filings.
The petition alleges 221 323 absentee ballots were improperly filed. Biden edged out Trump in Wisconsin by about 20 000 votes.
The Trump campaign and its supporters have filed lawsuits challenging Biden victories in Arizona, Pennsylvania, Georgia, Michigan and Nevada, so far without success.
On Monday, Wisconsin certified Biden as winner of the state, further dimming the Trump campaign's long-shot bid to overturn the results. The campaign is seeking withdrawal of that certification.
