Michigan Republicans say Green Party candidate Jill Stein's planned request for a hand recount of presidential votes could cost taxpayers up to $12 million, a dozen times what she will have to pay.

GOP attorney Eric Doster, who will help represent President-elect Donald Trump's campaign in the recount, said Tuesday he can't imagine the recount costing less than $10 to $12 million -- the cost of a statewide election.

Republicans cite "astronomical" costs of overtime pay, training, security and travel.

Stein plans to file her recount petition Wednesday and will pay the required $973,250.

Michigan GOP Chairwoman Ronna Romney McDaniel declines to say if Republicans will challenge the recount or take legal action, saying Stein hasn't yet made her request.

Trump won Michigan by 10,704 votes over Democrat Hillary Clinton.
