PORTLAND, Ore. — The Oregon Democratic Party wants the state's GOP to stop making automated calls that falsely tell voters their ballots won't count.

Democratic Party chair Frank Dixon says the Republican Party claimed the robo calls targeted "inactive" Republican voters. But Dixon says non-affiliated and Democratic voters received the calls.

Dixon says election officials across Oregon have been contacted by voters who received the calls and are concerned about their right to vote.

Oregon Secretary of State Jeanne Atkins says the state's GOP acknowledged making the calls.

The GOP said it arranged for automated calls on a county-by-county basis, but an investigation will determine if the party was the only source of the calls. There were variations in the scripts that voters heard.

Atkins says political parties can legally reach out to voters who are officially "inactive," but it's critical to make sure lists are up-to-date to avoid confusion.
