Updated. The Wisconsin Elections Commission said in a tweet Friday that Green Party presidential candidate Jill Stein has filed a petition for a recount of the state's votes after a respected Michigan election security expert and others said that though unlikely, the only way to know if the election was hacked in three key swing states was to recount the ballots. Petitions were filed by both Stein's campaign and that of "Rocky" Roque De La Fuente, the independent candidate for president for both the Reform Party and the American Delta Party. De La Fuente was on the ballot in 20 states and eligible for write-on in 17 other states.

It's unclear when the recount will begin. The recount petitions were filed hours before the deadline to do so in Wisconsin passed at 5 p.m. Friday. Stein said in a tweet that the recount will begin next week and that volunteers are needed to assist.

— Dr. Jill Stein (@DrJillStein) November 25, 2016 More about the process on Wisconsin Patch. Earlier on Patch: The well-respected University of Michigan election security expert who set off a firestorm with a hypothesis that the 2016 presidential election could have been hacked in three swing states has cleared some of the smoke, writing in a blog that the election was "probably not" hacked, but the only way to know for sure is to immediately audit the results.
