Maya Wiley has spent her adult life in and around the fight for civil rights, and these days she has the title to match: president and C.E.O. of the Leadership Conference on Civil and Human Rights, the coalition of more than 240 national organizations founded in 1950 as a partnership coming out of the Black liberation struggle. Among the groups in that coalition is the Southern Poverty Law Center. When Donald Trump’s Justice Department brought an 11-count fraud indictment against the S.P.L.C., and hauled the head of the group before the House Judiciary Committee last week for a daylong stream of bad-faith abuse from Jim Jordan and other MAGA Republicans, Wiley took it personally.
