Milwaukee election officials are recounting roughly 30,000 absentee ballots after issues were discovered with tabulator seals. City spokesperson Jeff Fleming told reporters the redo will likely cause delays in reporting those results in the key swing state.

Milwaukee election officials started all over again counting the city’s absentee ballots Tuesday afternoon after an observer noticed that the panel doors on the city’s 13 tabulators weren’t properly closed.

Officials in the city of Milwaukee, Wisconsin, say they are restarting the count of around 31,000 ballots due to a closing seal issue in one of the voting machines. The recount could delay the state's results.
