Wisconsin's election commission on 26 November said it "is preparing to move forward with a statewide recount of votes for President of the United States" after receiving petitions for a recount of votes in the presidential election from the Green Party campaign and another candidate.
"The Commission is preparing to move forward with a statewide recount of votes for President of the United States, as requested by these candidates," said Commission Administrator Michael Haas.
Former Green Party candidate Jill Stein had submitted papers to request a vote recount in Wisconsin, one of three battleground states won by Donald Trump and where she intends to challenge the results.
The commission said the deadline for completing a recount is 13 December, so its clerk will have to work quickly. It said it is still calculating the fee it will charge Stein's party for the arduous work of staging a recount.
Stein says she also plans to challenge the presidential election results in Pennsylvania and Michigan, where Trump won.
Her campaign has cited unspecified "anomalies" as grounds to mount a challenge in all three Rust Belt states.
Stein says she has raised more than USD 4.8 million of her USD 7 million goal.
