Christie had sent Jared's father, Charles Kushner, to jail in 2005. Charlie Kushner, pursued by the feds for an income tax cheat, set up a scheme with a prostitute to blackmail his brother-in-law, who was planning to testify against him. Various accounts, mostly offered by Christie himself, make Jared the vengeful hatchet man in Christie's aborted Trump administration career. It was a kind of perfect sweet-revenge story: the son of the wronged man (or, in this case--there's little dispute--the guilty-as-charged man) uses his power over the man who wronged his family.
