Early voting kicked off in Philadelphia on Tuesday where residents in the key battleground state were met with problems at the polls.
Voters who arrived at centers early Tuesday morning had to wait hours to cast their votes, according to a report from The Philadelphia Inquirer.
Delays were allegedly triggered by problems with the voter database, the newspaper reported, which prevented the processing and approval of mail-in ballot applications, and the printing of other materials.
Satellite election offices have been set up around the city to help facilitate voting by allowing i people to register to vote, and request, complete and submit mail-in ballots. Voters can also drop off ballots at satellite offices.
By midday, six of seven locations were online, according to the Inquirer. Additional locations are expected to open on a rolling basis.
City officials did not immediately return Fox News’ request for comment.
