According to Wisconsin law, incomplete absentee ballots may not be counted.
The Trump campaign said Wednesday that clerks issued absentee ballots to voters in Wisconsin without requiring an application, which they say is “in direct conflict with Wisconsin’s absentee voting safeguards.”
The campaign said that these ballots were issued during the two-week in-person absentee voting period, which ran between Oct. 20 and Nov. 1.
“The people of Wisconsin deserve to know whether their election processes worked in a legal and transparent way. Regrettably, the integrity of the election results cannot be trusted without a recount in these two counties and uniform enforcement of Wisconsin absentee ballot requirements. We will not know the true results of the election until only the legal ballots cast are counted,” Jim Troupis, counsel to the Trump campaign, said in a statement.
