The Trump administration’s election-integrity commission will have its first meeting on Wednesday to map out how the president will strip the right to vote from millions of Americans. It hasn’t gotten off to the strongest start: Its astonishing request last month that each state hand over voters’ personal data was met with bipartisan condemnation. Yet it is joined in its efforts to disenfranchise citizens by the immensely more powerful Justice Department.

Lost amid the uproar over the commission’s request was a letter sent at the same time by the Justice Department’s civil rights division. It forced 44 states to provide extensive information on how they keep their voter rolls up-to-date. It cited the 1993 National Voter Registration Act, known as the Motor-Voter law, which mandates that states help voters register through motor vehicle departments.

The letter doesn’t ask whether states are complying with the parts of the law that expand opportunities to register. Instead it focuses on the sections related to maintaining the lists. That’s a prelude to voter purging.

Usually the Justice Department would ask only a single state for data if it had evidence the state wasn’t complying with Motor-Voter. But a blanket request to every state covered under that law is virtually unprecedented. And unlike the commission, the Justice Department has federal statutory authority to investigate whether states are complying with the law.
