CHICAGO (AP) — Illinois officials have disclosed fresh issues with the state’s automatic voter registration program, saying at least one eligible voter who declined was registered to vote.

The program is already under fire for mistakenly registering over 500 people who indicated they weren’t U.S. citizens, of which 15 people voted in 2018 and 2019 elections.

State election officials said at least eight of the people had long voting histories and were likely U.S. citizens. Details on the new issues, disclosed at a State Board of Elections meeting, were scarce.

But it appeared at least one eligible person who declined was registered to vote.
