Repeal of exceptions to slavery and involuntary servitude

In the United States, the 13th Amendment to the United States Constitution prohibits slavery and involuntary servitude "except" as a punishment for a crime of which one has been convicted. In the latter 2010s, a movement has emerged to repeal the exception clause from both the federal and state constitutions. Colorado became the first state to repeal the exception clause from their state's constitution in 2018. Current bills to repeal similar clauses have passed in Utah and Nebraska after voters approved them in a referendum in 2020.
