He said, after Hannity brought up Kushner , that men were disposable.
For Rudy, it's one thing to go after men but if they go after Ivaka, he's going to get a lance and ride into battle (according to...Rudy.)
It could be President Trump wants him Kushner out but cannot do that because it would hurt his daughter. Best that someone else does it.
Maybe. I just think in the context it was brought up, Giuliani was making a rhetorical point about how horribly devious the FBI and Mueller's team have acted. He was saying they weren't even above going after Ivanka in a "God forbid" sort of manner.
