As policy adviser and counsel for Senate Minority Leader Mitch McConnell (R-Ky.), Brandi Wilson White has built strong working bonds throughout the Senate while coordinating the most pressing policy issues. A personal tragedy showed just how strong those ties could be.

White, 34, returned to her native Tennessee in March for the funeral of Tanner Hixson, her 22-year-old cousin who was more like a brother to her, and who died three hours after ingesting at a party a synthetic drug called 2C-I that was legal at the time.
