The Rev. Emanuel Cleaver III wants a second Civil Rights Movement in response to President Donald Trump and his fellow Republicans who are redrawing congressional district boundaries to increase their power in Washington.

In Missouri, the GOP's effort comes at the expense of Cleaver’s father, Rep. Emanuel Cleaver II, and many of his Kansas City constituents who fear that a national redistricting scramble will reverse gains Black Americans won two generations ago and leave them without effective representation on Capitol Hill.

“If we, the people of faith, do not step up, we are going to go back even further,” the younger Cleaver told the St. James Church congregation on a recent Sunday, drawing affirmations of “Amen” in the same sanctuary where his father, also a minister, launched his first congressional bid in 2004.

Trump and Republicans admit their partisan intent, emboldened by a U.S. Supreme Court that has allowed gerrymandering based on voters’ party leanings. Democratic-run California has proposed its own redraw to mitigate GOP gains elsewhere.

Yet new maps in Texas and Missouri -- drafted in unusual mid-decade redistricting efforts ahead of the 2026 midterm elections -- are meant to enable Republican victories by manipulating how districts are drawn. Civil rights advocates, leaders and affected voters say that amounts to race-based gerrymandering, something the Supreme Court has blocked when it finds minority communities are effectively prevented from electing representatives of their choice.
