Descendants of slaves who lived and toiled in southeastern Louisiana won a key ruling Thursday, April 28, 2022 allowing their legal challenge to go forward against a $400 million grain elevator planned along the Mississippi River, although the company behind the project said it would likely appeal. The terminal would be located not far from the Whitney Plantation, which documents the history of slavery. (AP Photo/Gerald Herbert)
