Someone with access to video and audio recordings of the calls shared them with The Times. Several participants confirmed the material’s authenticity.
In a statement to The Times about her work, Ms. Mitchell said her network “is about following the law and restoring the election process to one that is accurate, honest, and protects the secret ballot for all voters.”
Patrice Johnson, who sent the July invitation and oversees meetings of Michigan Fair Elections, referred requests for comment to Mr. Kaardal, who did not respond to queries.
Ms. Kiesel said in an interview that she wanted “to unify the United States through transparent and trusted elections.” She said that although she attended some meetings she is not a member of the coalition.
Election officials and governance experts say that if there is an erosion of trust in elections, Mr. Trump and his supporters are causing it. In Michigan, election officials say they are prepared for activists and lawyers to challenge close races in court by asking the judges to discard thousands of ballots in Democratic strongholds such as Detroit and Grand Rapids, and by filing lawsuits that seek to delay or block the certification of results.
On one recent Zoom meeting, Mr. Kaardal spoke about plans to try to force the entire governor’s race to be rerun. Mr. Colbeck last week called for a “full forensic audit” — a buzz word for the type of discredited, partisan examination of votes conducted in Arizona last year — regardless of the outcome.
