LITTLE ROCK, Ark. — Complaining about what he called indoctrination in schools, former President Donald Trump created a commission that promoted “patriotic” education and played down America’s role in slavery. Though he’s out of the White House and the commission has disbanded, the cause hasn’t died. Lawmakers in Republican states now are pressing for similar action.Proposals in Arkansas, Iowa and Mississippi would prohibit schools from using a New York Times project that focused on slavery’s legacy.
