The authority of the United States Congress over elections is extensive.[13][14] One feature of the proposed legislation is that convicted felons could not be denied the right to vote unless currently in prison.[15] Whether congressional authority extends this far is subject to disagreement,[16] with arguments being made for[17] and against.[18] Fourteen states have laws that indefinitely deny voting rights for some convicted felons, twenty-two do not restore voting rights until after parole and/or probation, and some states require payment of fines or restitution.[lower-alpha 1][19]
