Donald Trump’s presidential campaign has filed a lawsuit against Michigan officials, including Gov. Gretchen Whitmer, to block a directive to designate Veterans Affairs offices and other public facilities as voter registration sites.

Per the lawsuit, filed Monday, the Trump campaign seeks a “permanent injunction barring the state … from designating any VRAs [voter registration agencies] without express authorization from the Michigan Legislature.”

The directive — which would have instituted registration offices in Michigan Veterans Affairs, Worker’s Disability Compensation Agency and U.S. Small Business Administration offices — would have enabled Michiganders to check, update, and join the voter rolls more easily.
