Democracy Docket reports: Department of Homeland Security (DHS) Secretary Markwayne Mullin claimed his department is investigating 300,000 cases of potential noncitizens voting, with 1,600 active investigations. The Trump administration has made potential noncitizens voting its central message heading into the midterm elections Tuesday, repeatedly claiming without evidence that it is widespread. The administration has used those allegations to try to interfere with states’ constitutional authority to administer elections.
