Seminole County's election supervisor, Mike Ertel, found two suspicious voter registrations that were potentially submitted by Democratic-affiliated ACORN, according to this WESH article, broken first by an Orlando radio station WDBO.
The Republican National Committee's chief legal counsel, Sean Cairncross, said ACORN (due to loads of controversial voter-reigstration issues throughout the nation) was "quasi criminal" and said "these are the friends and allies of Barack Obama," a former community organizer who did work for ACORN in Illinois in the past.
ACORN's chief spokesman, Brian Kettenring, responded that Republicans and John McCain, whose campaign had attacked ACORN earlier in the week, were "trying to suppress the votes of minorities and new voters."
Hettenring said the group had already fired the petition gatherer linked to the cases Ertel was questioning. He said the group new the registrations were suspect and flagged that issue to the Orange County elections supervisor where the case originated. ACORN, he said, was required by law to submit the cards, regardless of what ACORN thought of their validity.
After Orange County imaged the documents into its system, it sent them to Seminole. But the sheet flagging the problem was detached in the process. So Ertel didn't see it. He did see a problem, though, when he checked the registration himself.
