In his 2016 memoir, “The Long Game,” Sen. Mitch McConnell wrote about descending from “a long line of hardworking and often colorful McConnells.” He failed to mention his slave-owning kin. It turns out that two of McConnell’s great-great-grandfathers — James McConnell and Richard Daley — owned at least 14 slaves in Limestone County, Alabama. Most of their slaves were female, according to investigative reporting by NBC News.
