Senate Joint Resolution 624, sponsored by Johnson, proposes an amendment to Article IV, Section 1 of the Tennessee Constitution to clarify that only U.S. citizens are eligible to vote in state, county, and municipal elections. The amendment stipulates that individuals must be at least eighteen years old, U.S. citizens, residents of Tennessee for a specified duration, and duly registered in their county of residence prior to elections. It emphasizes that these voting requirements must be uniform across the state, with no additional qualifications imposed on the right to vote.

Furthermore, the resolution grants the Tennessee General Assembly the authority to enact laws governing voter precincts and to ensure the integrity of elections. It mandates that the proposed amendment be referred to the next General Assembly for consideration and requires publication on the official websites of the Secretary of State and the General Assembly. The resolution also instructs the Senate Clerk to deliver a copy to the Secretary of State, excluding the final resolving clause from those copies.
