Stern, who works for the network as a judge on “America’s Got Talent”, said on his radio show that an NBC executive made a “threatening kind of comment” after Howard called Leno a “spineless maggot”.

Stern slammed Leno last Monday, after news Jay Leno had taken a pay-cut to save jobs on his show surfaced.

Howard said, “I got sort of a threatening kind of comment from one of the executives. I was done with Jay Leno, now I’m all fired up again”.

The radio host told his listeners, “It’s a smokescreen… Here’s what it really means, and you can take this to the bank: Jay Leno is a scumbag. That’s what that means. He’s a spineless maggot. Jay wanted to cut staff. He’s embarrassed to do it. He didn’t want to come off as a bad guy”.

Defiant Howard Stern later added, “Take my job away from me – who cares? I will never, ever, ever endorse Jay”.

Howard finished up his rant by stating, “I don’t answer to anybody, everyone knows that. That’s part of the game. And that’s why I’m a great judge – I would tell people if they sucked”.

Stern has made clear he has no qualms about his working relationship with the network.
