Comedian and civil rights activist Dick Gregory compared Walmart to the leader of Nazi Germany at a “living wage” rally in front of the D.C. City Council on Tuesday.

“When you look at Hitler and those thugs, you can put Walmart right next to them,” Gregory said in his speech to the 150 or so people at the event. The crowd was gathered to protest D.C. Mayor Vincent Gray’s veto of a bill that would have singled out the retail giant and forced it pay its employees $12.50 an hour.
