The petition Stein submitted to the state followed her attempts to compel officials to revisit the vote in Wisconsin and Pennsylvania. Stein has raised concerns about possible hacking or other irregularities in the vote tallying there. But she has presented no evidence of malfeasance.
In Michigan, Stein has cited the more than 75,000 ballots on which a choice for president was not recorded as a central point of concern. Voters are not required to pick a presidential candidate.
In a Wednesday afternoon news conference, Stein's team said it made a six-figure payment to the state of Michigan at the time it submitted its petition for a hand recount — covering the $125 cost per precinct state law requires candidates to submit, given the margin in the election.
But Republicans have raised concerns the total cost the state would have to absorb could exceed that amount significantly. At its news conference, Stein's team would not commit to covering the full cost.
“Shame on Jill Stein for throwing this taxpayer-funded temper tantrum, and shame on Democrats for not insisting that this ridiculous petition for a recount end immediately,” said Michigan Republican Party Chair Ronna Romney McDaniel in a statement. The state GOP, which spoke out Tuesday against a recall on behalf of the Trump campaign, did not immediately say whether it would challenge Stein's petition.
“The cost of this recount to Michigan taxpayers could easily reach into the millions of dollars. Based on Wisconsin’s estimate, Michigan taxpayers could be paying $4 million despite the $1 million the Green Party nominee must pay to have the recount," said Johnson in a statement.
Trump's victory over Democrat Hillary Clinton in Michigan was officially certified Monday. Officials said he won by 10,704 votes out of about 4.8 million cast. Stein finished well behind in Michigan, but won more support — about 51,000 votes — than the difference between Trump and Clinton.
“I hope the likelihood we'll see an outcome-determining shift is low. But we're never going to know,” unless there is a recount, said University of Michigan professor J. Alex Halderman, speaking as part of Stein's team.
In Wisconsin, where Trump defeated Clinton by a percentage point, state officials have said a recount will begin Thursday.
Clinton's campaign has joined Stein's recount effort, though it has said it does not expect the outcome of the election to change.
