Watch Chris Christie destroy Jared Kushner, Kushner's father, and New Jersey in just 10 seconds

Chris Christie and Jared Kushner's passive aggressive feud is now just downright aggressive.

Christie has repeatedly teased his fraught history with President Trump's son-in-law and senior adviser, which started when the then-New Jersey district attorney prosecuted Kushner's father for tax evasion in 2004. And in a Tuesday interview, Christie threw any hope of mending their relationship out the window.

The Kushner family is an obvious focus in Christie's new book Let Me Finish: Trump, the Kushners, Bannon, New Jersey, and the Power of In-Your-Face Politics, and Christie already debuted a section of the book describing how he learned Kushner takes his father's prosecution very personally. But on PBS's Firing Line, Christie said he doesn't quite understand why. After all, "it's one of the most loathsome, disgusting crimes that I prosecuted ... and I was the U.S. attorney in New Jersey," Christie said.

In his newly published book, Christie details a handful of times Kushner has apparently retaliated against him in the years after his father's guilty plea. Read more about them at The Week.
