Nebraska schools will have to teach about the Holocaust and other acts of genocide abroad under a bill passed by the Legislature Wednesday. But Legislative Bill 888 won't require education about “slavery, lynching and racial massacres in the United States," after lawmakers under pressure from the Governor's Office removed an amendment added to the bill earlier. State Sen. Justin Wayne of Omaha, who introduced the amendment , objected strenuously when lawmakers voted 27-13 to remove it on Monday. On Wednesday, he attempted unsuccessfully to add that language back into the bill before it passed on a 40-1 vote.
