President Donald Trump passed a Bill H.R. 1242 in recognition of Negroes 400 years of sojourning in America,

Then the Lord said to Abram, “You should know this: Your descendants will live in a country that is not their own. They will be strangers there. The people there will make them slaves and be cruel to them for 400 years. But then I will punish the nation that made them slaves. Your people will leave that land, and they will take many good things with them.
