The U.S. House Committee on Oversight and Reform has opened an investigation into the conduct of Georgia’s 2018 midterm elections, calling into question practices already under fire in multiple ongoing lawsuits here.

In letters to Gov. Brian Kemp and Secretary of State Brad Raffensperger, Chairman Elijah Cummings, D-Maryland, said his committee is investigating reports of “problems with voter registration, voter access, and other matters” affecting voters’ ability to cast a ballot during the November 2018 midterm election.
