The recount, at the request of outgoing US President Donald Trump, reconfirmed that Biden defeated President Donald Trump in the key swing state by more than 20,000 votes.
Dane County finished its recount on Sunday, according to the county clerk, a few days after Milwaukee County finished its.

Biden’s final tally in the state was 1,630,673 votes.
Trump had 1,610,065 votes.
