MADISON, Wis -

Wisconsin election officials estimate it will cost nearly $3.5 million to conduct a presidential recount in the state.

Green Party presidential candidate Jill Stein and Independent candidate Roque "Rocky" De La Fuente have both asked for a recount.

The Wisconsin Election Commission said Monday the recount will cost about $3.49 million based on county clerks' estimates. The commission says the clerks will have to hire thousands of temporary workers as well as work extra hours and weekends to meet a commission-imposed Dec. 12 deadline. The commission plans to certify the results the following day to meet the Dec. 13 federal deadline for finishing recounts.

Commission officials say one or both campaigns must pay $3.49 million by 4:30 p.m. Tuesday. The recount would then begin on Thursday.
