Mississippi finally got around to "officially" filing their state's ratification of the 13th Amendment.
The 13th Amendment took effect on December 6th 1865 (148 years ago) for most everyone else.
Mississippi claimed there was some sort of legal snafu since 1995 when the Mississippi legislators first approved the measure.
This is also comes 205 years after Thomas Jefferson signed a law against the importation of slaves on March 2, 1807.
(Two other late comers were the states of Delaware in 1901 and Kentucky in 1976)
