A Republican state lawmaker in Virginia stirred controversy on Tuesday when he used the occasion of the 40th anniversary of Roe v. Wade to compare abortion to the Holocaust.

State Sen. Dick Black (R-13th District) took to the floor and likened abortion clinics to Nazi concentration camps, saying at both places horrors "were taking place behind closed doors."

As reported by ThinkProgress, Black invoked the concentration camp Auschwitz and its infamous sign reading, "Arbeit Macht Frei," which translates to, "Work Makes You Free."
