MADISON, Wis. (CBS 58) – An email reportedly sent by a group known as “Kenosha for Trump” asked for volunteers to make phone calls to supporters of President Donald Trump in Pennsylvania to ask them to return ballots after Election Day.

The story was first reported by the Milwaukee Journal-Sentinel.

The email was reportedly sent on Thursday evening and included the contact information of staff members of the Republican Party of Wisconsin. A U.S. Supreme Court ruling allowed mailed absentee ballots sent by Election Day to be counted as long as they are received by 5 p.m. Friday, Nov. 6.

The issue was confirmed by the Trump campaign.

“Trump Victory continues to fight for election integrity at every level as we ensure that every legal vote for President Trump and other Republicans is counted fairly and accurately as required by law,” Trump Victory-Wisconsin spokesperson Anna Kelly told CBS 58 in an email statement. “The e-mail in question was sent by an unaffiliated local group and any related social media posts have been taken down.”

The Trump campaign said it is making calls into Pennsylvania to ask voters whether they returned absentee ballots, and if so, when those ballots were returned. The campaign says the email “falsely” stated the campaign was asking voters to return ballots after Election Day.

The issue comes as President Trump has baselessly called into question the electoral process and integrity across the country, including making claims without evidence that ballots cast after Election Day are being counted.
