Washington (CNN) Former New Jersey Gov. Chris Christie said that "one of the most loathsome, disgusting crimes" he prosecuted more than a decade ago when he was a US attorney was committed by the father of President Donald Trump's son-in-law and top adviser Jared Kushner.

Christie, who chaired Trump's transition team for a short time, has recently been drawing attention to his relationship with Kushner and his father, the real estate developer Charles Kushner, while promoting his new book, "Let Me Finish."

According to excerpts of the book reported on by Axios and The Guardian , Christie claims that the younger Kushner was behind his departure from Trump's inner circle after the 2016 election, writing that he was "still apparently seething over events that had occurred a decade ago."

In an interview with PBS's Margaret Hoover on "Firing Line" released Tuesday, Christie unloads on the senior Kushner for the crimes that he prosecuted him for.
