The Democratic National Committee filed a motion in federal court Wednesday alleging the Republican Party had violated a longstanding consent decree barring “ballot security” measures that could be used to intimidate voters.

The DNC’s legal team is asking for a federal judge to prevent any possible GOP’s “ballot security” measures, and to hold the Republican Party in contempt for allegedly violating the 1981 consent decree, which resulted from Republican officials reportedly intimidating minority voters under the guise of keeping the elections clean.
