For Kushner and Affinity, those puzzles have gotten trickier. When Trump tapped him last year to help with Ukraine and Gaza, Kushner handed off management at Affinity to two deputies: Luis Videgaray, an ex-finance minister of Mexico, and Asad Naqvi, a former banker at Lazard, according to a person familiar with the matter; Lauren Key, Affinity’s chief financial officer, provides additional support. That team meets with companies and holds quarterly meetings with investors.
