Pamela Moses, the founder of the Black Lives Matter Memphis chapter and a former Democratic mayoral candidate, received a six-year and one-day prison sentence for illegally registering to vote, the New York Post reports.

The activist was ineligible to vote due to previous felony convictions in 2015 but she said she was unaware she permanently forfeited her voting rights when she pleaded guilty at the time, The Washington Post reports

The corrections department and the county election commission approved her 2019 voter registration application and verified that she completed her probation, thereby restoring her voting privileges. Officials later admitted they made a mistake and her voting privileges had not been restored.
