(JTNews) – The Colorado Secretary of State’s Office mailed voter-registration instructions to roughly 30,000 non-citizens living in the state.

The agency said it is attempting to determine why the registration postcards were sent to people who had non-citizen state driver’s licenses, Colorado Public Radio reported last week.

Colorado makes clear the state’s online-voter registration system will block the processing of applications for anyone who isn’t a U.S. citizen.

“Make sure your voice is heard this November,” reads the postcards, which also include instructions on how to “Register to VOTE today.”

The agency says it is conducting an internal review on the matter and “will take any corrective action that is warranted.”

The postcards are believed to have been sent as a result of a formatting error in a department of motor vehicles database.
